Fiery Last-Lap Daytona Crash Injures 15 Fans

A fiery last-lap crash at the Daytona International Speedway injured a number of spectators today, who were seen being carried away from the stands on stretchers.

Fifteen spectators were taken to the hospital, according to ESPN, with one on the way to surgery with head trauma.

The 12-car crash happened moments before the end of the Nationwide race, and on the eve of the Daytona 500, one of NASCAR's biggest events.

The crash was apparently triggered when driver Regan Smith's car, which was being tailed by Brad Keselowski on his back bumper, spun to the right and shot up the track. Smith had been in the lead and said after the crash he had been trying to throw a "block."

Rookie Kyle Larson's car slammed into the wall that separates the track from the grandstands, causing his No. 32 car to go airborne and erupt in flames.

When a haze of smoke cleared and Larson's car came to a stop, he jumped out uninjured.

His engine and one of his wheels were sitting in a walkway of the grandstand.

"I was getting pushed from behind," Larson told ESPN. "Before I could react, it was too late."

Driver Michael Annett was taken to the hospital after he slammed head-on into a barrier during the chaos. NASCAR officials told ESPN the driver was awake and alert.

Tony Stewart pulled out the win, but in victory lane, what would have been a celebratory mood was tempered by concern for the injured fans.

"We've always known this is a dangerous sport," Stewart said. 'But it's hard when the fans get caught up in it."

Rusty rocks reveal ancient origin of photosynthesis

SUN-WORSHIP began even earlier than we thought. The world's oldest sedimentary rocks suggest an early form of photosynthesis may have evolved almost 3.8 billion years ago, not long after life appeared on Earth.

A hallmark of photosynthesis in plants is that the process splits water and produces oxygen gas. But some groups of bacteria oxidise substances like iron instead – a form of photosynthesis that doesn't generate oxygen. Evolutionary biologists think these non-oxygen-generating forms of photosynthesis evolved first, giving rise to oxygen-generating photosynthesis sometime before the Earth's atmosphere gained oxygen 2.4 billion years ago (New Scientist, 8 December 2012, p 12).

But when did non-oxygen-generating photosynthesis evolve? Fossilised microbial mats that formed in shallow water 3.4 billion years ago in what is now South Africa show the chemical fingerprints of the process. However, geologists have long wondered whether even earlier evidence exists.

The world's oldest sedimentary rocks – a class of rock that can preserve evidence of life – are a logical place to look, says Andrew Czaja of the University of Cincinnati in Ohio. These rocks, which are found in Greenland and date back almost 3.8 billion years, contain vast deposits of iron oxide that are a puzzle. "What could have formed these giant masses of oxidised iron?" asks Czaja.

To investigate, he analysed the isotopic composition of samples taken from the oxidised iron. He found that some isotopes of iron were more common than they would be if oxygen gas was indiscriminately oxidising the metal. Moreover, the exact isotopic balance varied subtly from point to point in the rock.

Both findings make sense if photosynthetic bacteria were responsible for the iron oxide, says Czaja. That's because these microbes preferentially oxidise only a small fraction of the dissolved iron, and the iron isotopes they prefer vary slightly as environmental conditions change (Earth and Planetary Science Letters, doi.org/kh5). His findings suggest that this form of photosynthesis appeared about 370 million years earlier than we thought.

It is "the best current working hypothesis for the origin of these deposits", says Mike Tice of Texas A&M University in College Station – one of the team who analysed the 3.4-billion-year-old microbial mats from South Africa.

William Martin at the University of Düsseldorf, Germany, agrees. "Anoxygenic photosynthesis is a good candidate for the isotope evidence they see," he says. "Had these fascinating results been collected on Mars, the verdict of the jury would surely remain open," says Martin Brasier at the University of Oxford. "But [on Earth] opinion seems to be swinging in the direction of non-oxygen-generating photosynthesis during the interval from 3.8 to 2.9 billion years ago."

Street theatre catches fancy of India's youth

NEW DELHI: Theatre, which is a big part of Indian tradition, has evolved over the years.

An ancient form of theatre which was once practised to drive home political agendas is today being extensively used to create awareness of social issues in the country.

The growing prominence of street theatre has also caught the fancy of the young.

She moves about with her arms stretched, hair strewn and in ragged clothes.

Delivering her dialogue in a shrill tone, she trails around throwing questions at the surprised audience.

This is not a scene from a Bollywood movie but a snippet of a street play on the status of women in India.

With no stage, arch lights, make-up and minimum props, the medium of street theatre - also known as the people's theatre - has gained wide-spread acceptance and popularity in modern India.

As realistic as it gets, street theatre has become a popular medium to spread awareness about pressing social and political issues in the country.

Dramatist and film-maker, Siddhant Malhotra, said: "I think it is the best possible way to spread awareness, because there is a group of 100 people watching your play.

"You can interact with them, you can engage them right on and they will get your point. By performing a 30-minute play, if you're engaging 100 people at a time, you're changing 100 people at a time which even an advertisement cannot do."

As the name suggests, street plays can be performed anywhere on busy roads, market places or outside offices.

This enables it to reach out to the majority of people for whom theatre is not accessible, like in rural and backward areas.

The shows are not ticketed or pre-scheduled, as the main aim is not to make money but to reach out to as many people as possible.

Often packed with dramatic dialogues, catchy songs and hyperbole, street plays have a telling effect on the masses.

Young dramatists, who often use this medium to generate awareness, feel that a casual approach and lack of a formal atmosphere help them in connecting with the viewers.

Ayushi Kumar, a student and dramatist, said: "Street theatre is one of the art form where actually we are so close to the audiences that we are almost with them. So we can talk, we can connect and to bring that feeling in which they can reflect on themselves. I believe street is the strongest form of theatre for that."

Another student and dramatist, Shiva Sreenivasan, said: "You have a lot of fun when you watch it and when you are having fun you are also getting a message in your head. That is the most important thing. You're just not there and watching it like a niche audience that watches a street play. It's not like that.

"The thing is that we address proper moral issues for the society and for the people of the country. So, it is very easy for us to connect with them, explain our point and get our point through."

Street theatre practitioners hope that the tradition can help to bring about long-term change to Indian society, which despite its progress is reeling under the darkness of social evils like rape, dowry and child marriage.

STORY HIGHLIGHTS

• Brittni Garcia didn't think her weight was a problem until she couldn't fit into her "fat shorts"


• At 235 pounds, Garcia always felt like she stood out from her sorority sisters in college


• Garcia shed 107 pounds, and now promotes weight training and a healthy diet


• Do you have a weight loss success story? Share it with CNN iReport

(CNN) -- Brittni Garcia's family didn't go out for walks; they went out for dinner. And when they were at home, they enjoyed watching movies, playing board games and eating big Mexican-style home-cooked meals.

This lazy lifestyle led Garcia to weigh more than 200 pounds by the eighth grade.

"My mom always said, 'You are a big girl. You are just big-boned,'" said the 25-year-old information specialist. "So I just accepted it."

Through high school and college, her weight continued to rise. But even at 235 pounds, Garcia didn't think her weight was a problem -- until she couldn't fit into her "fat shorts" anymore.

That was December 2009.

It was a typical night for Garcia. She was studying for finals in her sorority house at Eastern Illinois University and wanted to change into some comfortable clothing. She found her red pajama XXL shorts that she normally wore to bed.

As she struggled to pull them up, she realized they were too tight and uncomfortable -- her "big, comfy shorts" no longer fit.

"Tons of emotions ran through my head," she said. "I was afraid that was the way my life was going to be."

That's when Garcia's mentality changed. Being overweight was no longer normal for her.

Heart disease runs in her family, and she realized it was time to address her weight now before it turned into a bigger health problem.

"I wanted to lose weight to challenge myself and show myself I can change, and not change for the world," Garcia wrote in her iReport. "This time, it was for me."

Getting in shape wasn't going to be easy. Going to the gym had been one of her biggest fears for a long time. She was self-conscious about how she looked and sounded when she ran.

"It was hard for me to breathe," Garcia said. "It was embarrassing."

Embarrassment about her weight extended to other areas of her life. Although she was president of her sorority, Garcia always felt like she stood out.

"All the sorority girls had cookie-cutter form, and I looked different," she said. "It was really hard for me to connect."

Garcia's involvement in Greek life perpetuated her unhealthy habits; she often went to bars and restaurants to mingle with her college friends. It was difficult to break the cycle, but she found supportive friends who also hit the gym.

"What I tell people is that you find new friends at the gym," she said. "If you don't have the support, it's really hard to do it on your own."

Garcia found one of her biggest supporters through her sorority. She met Nicholas Monreal at a Greek function, and they began dating when she was at her heaviest. But the days of social functions, bar visits and restaurant outings are long gone for the couple.

"He was there when I realized I wanted to change," she said. "To this day, our dates are to the gym. We see excitement in going on walks and runs."

The couple has been together for four years; he proposed in December. Monreal has noticed a significant difference in Garcia over the past few years -- not just physically.

"She's more energetic ... and she's more willing to try new things," he said "She's just working very hard, and she's a better person for it."

On the right track

Since the beginning of 2010, Garcia has lost 107 pounds.

There were setbacks, the biggest of which came this past August when she was in a car accident. She completed three months of physical therapy and wasn't able to go to the gym and do her daily routines for a month and a half.

She was angry at first -- mad at the person who hit her car and stalled her progress at the gym.

But she got over her initial anger, and Garcia went on a walk. This time, she wasn't alone. Her fiance, her parents, her sisters and her aunt encouraged her to stay active. As a result, Garcia went on walks with them and did yoga at a gym.

After getting back on track with her daily workouts, Garcia realized she also had to better manage her eating habits.

"For the longest, I would go to the gym and go home to eat whatever I wanted," she said. "That's not how it works. I had to learn to eat differently and to learn to like new foods."

She started doing research on proper nutrition. She read books and online articles, shopped at health foods stores and learned to prepare meals that helped her maintain a healthy diet.

Now for two hours every Sunday, Garcia grills chicken, cooks vegetables and packs fresh fruit in preparation for the upcoming week.

"(I) make eating as simple as possible," she said. "If there are a lot of ingredients, I don't want it."

The next step

Down to 128 pounds, Garcia has been left with a lot of loose skin -- particularly around her stomach. She is doing CrossFit exercises and weight training to tighten up the area.

She's also checking off some other goals.

One of the most rewarding moments in Garcia's weight loss journey was completing her first 5K run in 27 minutes.

When she first started training, running three miles took her 48 minutes. Today, she can complete it in less than 25.

"I hadn't been able to walk a lap, let alone run it," she said. "And now when I finish a workout, I really get emotional and I can't believe that I could do it."

She isn't stopping there. Garcia wants to complete a half marathon as well as the Warrior Dash in June. As a result, she might take a pool break in between.

"I really want to fit in my bikini comfortably this summer," she said.

Today, Garcia doesn't shop at plus size clothing stores anymore. She was able to drop from a size 22 to a size 6.

And what happened to her XXL "fat shorts?" She ditched them for a pair of small exercise shorts.

To those just starting their weight-loss journey, she offers this advice:

"Once you start, don't give up. The hardest thing to do is to continue. If you have a bad day, don't make it a bad week."

Wash. state governor: 6 underground nuclear tanks leaking

Updated 8:11 PM ET

YAKIMA, Wash. Six underground tanks that hold a brew of radioactive and toxic waste at the nation's most contaminated nuclear site are leaking, federal and state officials said Friday.

Washington Gov. Jay Inslee said the leaking material poses no immediate risk to public safety or the environment because it would take a while — perhaps years — to reach groundwater.

But the leaking tanks raise new concerns about delays for emptying them and strike another blow to federal efforts to clean up south-central Washington's Hanford nuclear reservation, where successes often are overshadowed by delays, budget overruns and technological challenges.

Department of Energy spokeswoman Lindsey Geisler said there was no immediate health risk and said federal officials would work with Washington state to address the matter.

Washington state Gov. Jay Inslee, right, is joined by Maia Bellon, director of the Department of Ecology, at a news conference to discuss a tank leak at Hanford Nuclear Reservation, on Friday, Feb. 15, 2013, in Olympia, Wash.

State officials just last week announced that one of Hanford's 177 underground tanks was leaking 150 to 300 gallons a year, posing a risk to groundwater and rivers. So far, nearby monitoring wells haven't detected higher radioactivity levels.

Inslee traveled to Washington, D.C., this week to discuss the problem with federal officials. He said Friday that he learned in meetings that six tanks are leaking waste.

"We received very disturbing news today," the governor said. "I think that we are going to have a course of new action and that will be vigorously pursued in the next several weeks."

The federal government built the Hanford facility at the height of World War II as part of the Manhattan Project to build the atomic bomb. The remote site produced plutonium for the bomb dropped on Nagasaki, Japan, and continued supporting the nation's nuclear weapons arsenal for years.

Today, it is the most contaminated nuclear site in the country, still surrounded by sagebrush but with Washington's Tri-Cities of Richland, Kennewick and Pasco several miles downriver.

Hanford's tanks hold some 53 million gallons of highly radioactive waste — enough to fill dozens of Olympic-size swimming pools — and many of those tanks are known to have leaked in the past. An estimated 1 million gallons of radioactive liquid already leaked there.

The tanks also are long past their intended 20-year life span — raising concerns that even more tanks could be leaking — though they were believed to have been stabilized in 2005.

Inslee said the falling waste levels in the six tanks were missed because only a narrow band of measurements was evaluated, rather than a wider band that would have shown the levels changing over time.

"It's like if you're trying to determine if climate change is happening, only looking at the data for today," he said. "Perhaps human error, the protocol did not call for it. But that's not the most important thing at the moment. The important thing now is to find and address the leakers."

There are legal, moral and ethical considerations to cleaning up the Hanford site at the national level, Inslee said, adding that he will continue to insist that the Energy Department completely clean up the site.

He also stressed the state would impose a "zero-tolerance" policy on radioactive waste leaking into the soil.

Cleanup is expected to last decades and cost billions of dollars.

The federal government already spends $2 billion each year on Hanford cleanup — one-third of its entire budget for nuclear cleanup nationally. The Energy Department has said it expects funding levels to remain the same for the foreseeable future, but a new Energy Department report released this week includes annual budgets of as much as $3.5 billion during some years of the cleanup effort.

Much of that money goes toward construction of a plant to convert the underground waste into glasslike logs for safe, secure storage. The plant, last estimated at more than $12.3 billion, is billions of dollars over budget and behind schedule. It isn't expected to being operating until at least 2019.

Given those delays, the federal government will have to show that there is adequate storage for the waste in the meantime, Inslee said.

"We are not convinced of this," he said. "There will be a robust exchange of information in the coming weeks to get to the bottom of this."

Inslee and Oregon Gov. John Kitzhaber have championed building additional tanks to ensure safe storage of the waste until the plant is completed. Sen. Ron Wyden, D-Ore., said earlier this week that he shares their concerns about the integrity of the tanks but he wants more scientific information to determine it's the correct way to spend scarce money.

Tom Carpenter of Hanford Challenge, a Hanford watchdog group, said Friday it's disappointing that the Energy Department is not further along on the waste treatment plant and that there aren't new tanks to transfer waste into.

"None of these tanks would be acceptable for use today. They are all beyond their design life. None of them should be in service," he said. "And yet, they're holding two-thirds of the nation's high-level nuclear waste."

Wyden noted the nation's most contaminated nuclear site — and the challenges associated with ridding it of its toxic legacy — will be a subject of upcoming hearings and a higher priority in Washington, D.C.

Jodi Arias' Friends Believe in Her Innocence

Accused murderer Jodi Arias believes she should be punished, but hopes she will not be sentenced to death, two of her closest friends told ABC News in an exclusive interview.

Ann Campbell and Donavan Bering have been a constant presence for Arias wth at least one of them sitting in the Phoenix, Ariz., courtroom along with Arias' family for almost every day of her murder trial. They befriended Arias after she first arrived in jail and believe in her innocence.

Arias admits killing her ex-boyfriend Travis Alexander and lying for nearly two years about it, but insists she killed Alexander in self defense. She could face the death penalty if convicted of murder.

Nevertheless, she is aware of the seriousness of her lies and deceitful behavior.

The women told ABC News that they understand that Arias needs to be punished and Arias understands that too.

"She does know that, you know, she does need to pay for the crime," Campbell said. "But I don't want her to die, and I know that she has so much to give back."

The lies that Arias admits she told to police and her family have been devastating to her, Bering said.

""She said to me, 'I wish I didn't have to have lied. That destroyed me,'" Donovan said earlier this week. "Because now when it's so important for her to be believed, she has that doubt. But as she told me on the phone yesterday, she goes, 'I have nothing to lose.' So all she can do is go out there and tell the truth."

During Arias' nine days on the stand she has described in detail the oral, anal and phone sex that she and Alexander allegedly engaged in, despite being Mormons and trying to practice chastity. She also spelled out in excruciating detail what she claimed was Alexander's growing demands for sex, loyalty and subservience along with an increasingly violent temper.

Besides her two friends, Arias' mother and sometimes her father have been sitting in the front row of the courtroom during the testimony. It's been humiliating, Bering said.

"She's horrified. There's not one ounce of her life that's not out there, that's not open to the public. She's ashamed," she said.

Mood-sensing smartphone tells your shrink how you feel

PEOPLE with anxiety, depression or stress are often asked to record their mood changes throughout the day, helping psychologists fine-tune their treatment. But they often forget, recording only sparse information at best. Now an emotion-sensing smartphone app that automatically generates someone's "mood diary" could give psychologists all the data they need.

It's the brainchild of Matt Dobson and Duncan Barclay, founders of speech recognition firm EI Technologies, based in Saffron Walden, UK. Instead of relying on people writing diaries, the app, called Xpression, listens for telltale changes in a person's voice that indicate whether they are in one of five emotional states: calm, happy, sad, angry or anxious/frightened. It then lists a person's moods against the times they change, and automatically emails the list to their psychologist at the end of the day.

To work, the app has to be always on, listening out for the user's voice once every second, whether they are talking to family, friends, colleagues or even pets. It also listens in on phone calls. If the user is silent, the app does nothing. Crucially for the users' privacy, it doesn't record their words, instead seeking out telltale acoustic features – like pitch – that are indicative of emotional state.

This kind of emotion recognition via voice pattern already works well and is a "hot area" of research, says Stephen Cox, head of the speech processing lab at the University of East Anglia in Norwich, UK, who is scientific adviser for the firm.

Initially, Xpression will send 200-millisecond-long acoustic snapshots to a remote server where a machine-learning system will work out a person's emotional state before sending it back to the app for storage. Factors like voice loudness, intensity, changes in pitch and speaking pace allow the system to accurately estimate somebody's emotional state. "We extract acoustic features and let the machine-learning system work it out," says Cox. This ability will be built into the app itself eventually, says Dobson.

There's a strong need for this kind of technology, says Adrian Skinner, a clinical psychologist with the UK's National Health Service in Harrogate, North Yorkshire. "With conditions like depression, people tend to stop doing things like filling in mood diaries. If this app gives us more complete diaries it could help us better find the day-to-day triggers that raise or lower a patient's mood," he says.

The firm is a finalist in a UK government competition to identify the nation's top mobile tech company, to be judged on 26 February. An insurance company has already expressed an interest in using the app to ensure the workplace stress therapy it pays for is effective. Clinical trials are due to take place later this year.

Asian markets mixed, yen claws back some losses

HONG KONG: Asian markets were mixed on Friday, with Tokyo dragged by a further strengthening in the yen, while the euro faced selling pressure following weak eurozone data.

Losses on Wall Street added to the gloom after disappointing US economic figures, while traders were casting an eye to a general election in Italy at the weekend.

Tokyo fell 0.50 per cent by the break, Hong Kong lost 0.85 per cent and Shanghai was off 0.16 per cent, but Sydney jumped 1.26 per cent and Seoul added 0.23 per cent.

While some markets were lifted by bargain hunting, sentiment was still weak after minutes from the US Federal Reserve's latest policy meeting that stoked fears it could end its huge monetary easing sooner than expected.

Japan's Nikkei was weighed as the yen rose against the dollar and euro, clawing back some of the massive losses it has seen in recent months.

In early Tokyo trade the dollar sat at 93.04 yen, compared with 93.11 yen in New York Thursday. However, the Japanese unit -- which has lost about 17 per cent against the greenback since November -- is much stronger than the 94.00 yen seen at the start of the month.

And the euro fetched 122.78 yen, against 122.81 yen, and well off the 125.50 yen earlier in the week.

The euro bought $1.3189, against $1.3188 in New York Thursday and well short of the $1.3350 on Monday.

The euro came under increased pressure after a leading eurozone growth indicator showed private business activity hit a two-month low in February.

The Purchasing Managers' Index published by London-based Markit fell to 47.3 in February from 48.6 the previous month.

The February figures contrasted sharply with an improvement in the previous three months, which saw it hit a 10-month high in January.

There is nervousness about Sunday's Italian election, which is too close to call and which markets have warned could send the economy back into crisis if there is no clear winner.

Some fear a return of former prime minister Silvio Berlusconi, which could lead to the dismantling of recent economic reforms that have helped draw the country back from economic crisis.

On Wall Street the Dow was down 0.34 per cent, the S&P 500 eased 0.63 per cent and the Nasdaq dropped 1.04 per cent after worse-than-expected US business activity data, while new claims for unemployment benefits rose last week.

Consumer prices also came in flat for a second month in a row in January, underscoring weak inflationary pressures in the world's number one economy.

Meanwhile, traders are becoming increasingly concerned about the lack of progress in Washington on a deal to avert the sequester, deep government spending cuts economists say will slow US growth.

Oil prices rose, with New York's main contract, light sweet crude for delivery in April gaining 17 cents to $93.01 a barrel and Brent North Sea crude for delivery in April adding 17 cents to $113.70.

Gold was at $1,581.30 at 0247 GMT, compared with $1,568.41 late Thursday.

Drew Peterson gets 38 years for ex-wife's murder

STORY HIGHLIGHTS

• NEW: Drew Peterson's lawyer says his client feels the system he served failed him


• NEW: Kathleen Savio's kin say he "battered her to the very end," is "going to hell"


• The Chicago-area police sergeant was convicted of murdering his third wife


• He is sentenced to 38 years in prison and will get credit for nearly 4 years served

(CNN) -- After years policing Illinois streets for criminals, Drew Peterson is now among them -- and will be for more than three decades, a judge ruled Thursday.

Will County Judge Edward Burmila sentenced Peterson to 38 years in prison in the murder of his third ex-wife, Kathleen Savio, said state's attorney spokesman Charles B. Pelkie.

The former Chicago-area police sergeant will get credit for the nearly four years that he has been in custody, according to Pelkie, a spokesman for Will County State's Attorney James Glasgow. He could have received as many as 60 years in prison; Illinois does not have a death penalty.

"The reason that I never looked Drew Peterson in the eye is because I never acknowledged his existence," said Glasgow, describing the convict as a "cold-blooded killer."

"But I looked him in the eye today," the prosecutor said. "He knows that we did our job."

Peterson was convicted of murder in September but had fought for a new trial, an effort that Burmila denied Thursday, just before the sentencing.

Peterson's lawyers promised Thursday that they would press on with their appeal and expressed confidence they would prevail. They stood by their client, who defiantly claimed in court that he didn't kill Savio.

"Wouldn't you be angry if you were wrongly convicted?" said one of his attorneys, Steve Greenberg.

"In this case, (the prosecution) changed everything ... How would you feel if you were railroaded?"

Savio was found dead in her dry, clean bathtub on March 1, 2004. Prosecutors said Peterson killed her; the defense contended that she fell, hit her head and drowned.

The case did not grab headlines until after Peterson's fourth wife, Stacy, disappeared in October 2007. It was during the search for Stacy Peterson -- who still has not been found -- that investigators said they'd look again into Savio's death, which was initially ruled an accidental drowning.

Authorities altered their judgment and ruled Savio's death a homicide in February 2008, setting the stage for the first-degree murder trial last year of Peterson, a former police officer in Bolingbrook, Illinois.

A Will County jury ultimately convicted him of murder after nearly 14 hours of deliberation.

That was four months ago. On Thursday, all the parties were back in court to see whether Peterson would get a new trial or, if not, what his sentence would be.

Perhaps the most emotional part of this court proceeding was Peterson's long and emotional remarks, which were interrupted at times by shouts from Savio family members, several of whom were asked to leave the courtroom.

He unloaded "pent-up anger" that had built up over time -- against Savio and her family, the legal process, the media, even a TV movie about the case, according to his attorneys and the prosecutor. Above all, Peterson loudly insisted that he did not kill Savio.

Why was he upset? One of his lawyers, David Peilet, said part of it has to do with Peterson feeling the system that he served -- as a military veteran and longtime police officer -- had failed him.

"(He is angry) especially when you are somebody who has defended the Constitution and served and protected the public, now being faced with the same system coming up and biting (you) in the butt," Peilet said.

Glasgow, the state's attorney, had a different take. He called Peterson's remarks "pathetic," especially in how he "attacked" Savio and her mental state.

"Just depraved," the prosecutor said. "... We all got an opportunity to see a psychopath reveal himself in open court."

It was a sentiment echoed by the victim's sister, Susan Doman. She said she couldn't stand to hear "the devil" demean her sister, almost nine years after her death.

"He battered her to the very end."

Pam Bosco, a spokeswoman for Stacy Peterson's family, lauded the prosecution for making "this world a safer, better place" by fighting to convict Peterson and expressed hope he'd next be held accountable for what happened to his fourth wife.

"It's not over for us, but of course, a win for the Savio family is a win for the Stacy Peterson family," Bosco said. "We have a long journey ahead. We still want to see justice for Stacy. We won't give up."

Several Savio family members specifically mentioned Stacy when they addressed reporters late Thursday afternoon in Joliet.

Henry Savio Jr., a brother of Kathleen Savio, said Stacy Peterson's relatives "deserve the same thing that we're getting right now: justice."

As to Peterson's fate, Henry Savio said he wanted him to "stay in jail forever, to die there."

"(Then) he is going to go to hell," the victim's brother said. "And my sister is going to be watching him."

CNN's Elwyn Lopez, Carma Hassan and Michael Christian, from the InSession division of CNN's sister network TruTV, contributed to this report.

Midwest swaddled in blanket of snow

ST. LOUIS Powdery snow, up to a foot and a half in some places, bombarded much of the nation's midsection Thursday, impeding travel and shutting down airports, schools and state legislatures.

The widespread winter storm system swirled to the north and east Thursday night, its snow, sleet and freezing rain prompting winter storm warnings in Kansas, Nebraska, Iowa, Missouri and Illinois.

Corey Mead, a meteorologist with the National Weather Service's Storm Prediction Center in Norman, Okla., said the winter storm would be centered in the upper Midwest by Friday morning.

"Even across Kansas, the snowfall rates should continue to taper off through the evening," Mead said.

Chris Suchan, chief meteorologist at CBS affiliate KCTV Kansas City, told "CBS Evening News" anchor Scott Pelley Thursday that the worst is over with. "This morning we had widespread thundersnow from Levenworth, Kansas [and] Overland Park to Warrensburg, Missouri," Suchan said. "Snowfall rates of 2 to 3 inches per hour brought this area to its knees with our motoristsbridges were closed for a while.

The sound and fury of "thundersnow"

"Now what we're anticipating is another round for this evening, perhaps another 2 to 4 inches of snowfall, some freezing drizzle right now, and wind chills in the single digits. The storm total for us is about 8 to 12-14 inches of snowfall for Kansas City."

The system left behind impressive snow accumulations, especially in western Kansas, where 17 inches fell in Hays.

Several accidents and two deaths were blamed on icy and slushy roadways; two people died in crashes Wednesday. Most schools in Kansas and Missouri, and many in neighboring states, were closed. Legislatures shut down in Kansas, Missouri, Arkansas, Nebraska and Iowa.

National Weather Service meteorologist Scott Truett said the "thundersnow" that rumbled through Kansas and Missouri earlier Thursday was the result of an unstable air mass, much like a thunderstorm.

"Instead of pouring rain, it's pouring snow," Truett said. And pouring was a sound description, with snow falling at a rate of 2 inches per hour or more in some spots.

Topeka got 3 inches of snow in one 30-minute period, leaving medical center worker Jennifer Carlock to dread the drive home.

"It came on fast," Carlock said as she shoveled around her car. "We're going to test out traction control on the way home."

Snow totals passed the foot mark in many places: Monarch Pass, Colo., had 17-and-a-half inches, the Kansas cities of Hutchinson, Macksville and Hanston all saw 14 inches, and Wichita, Kan., had 13 inches. A few places in far northern Oklahoma saw between 10 to 13-and-a-half inches of snow. Missouri's biggest snow total was 10 inches, shared by the Kansas City metropolitan area, Rockport in the northwest corner and Moberly in the central part of the state.

Transportation officials in affected states urged people to simply stay home.

"If you don't have to get out, just really, please, don't do it," Kansas Gov. Sam Brownback said.

Drivers were particularly warned away from the Kansas Turnpike, which had whiteout conditions. Interstate 70 was also snow-packed, and a 200-mile stretch was closed between Salina and Colby.

Cases of wine and beer -- as well as bottles of scotch and whiskey -- were flying off the shelves at Ingersoll Wine and Spirits ahead of the storm's arrival in Des Moines, Iowa.

"A lot of people have been buying liquor to curl up by the fire," wine specialist Bjorn Carlson said.

NWS forecasts showed 3 to 9 inches of snow were expected in Iowa overnight, and Nebraska will see an additional 2 to 5 inches.

Heavy, blowing snow caused scores of businesses in Iowa and Nebraska to close early, including two malls in Omaha, Neb. Mardi Miller, manager of Dillard's department store in Oakview Mall, said most employees had been sent home by 4 p.m., and she believed "only two customers are in the entire store."

The storm brought some relief to a region that has been parched by the worst drought in decades.

Vance Ehmke, a wheat farmer near Healy, Kan., said the nearly foot of snow was "what we have been praying for." Climatologists say 12 inches of snow is equivalent to about 1 inch of rain, depending on the density of the snow.

"The big question is, `Is the drought broke?' " Ehmke asked.

Near Edwardsville, Ill., farmer Mike Campbell called the precipitation a blessing after a bone-dry growing season in 2012. He hopes it is a good omen for the spring.

"The corn was just a disaster," Campbell said of 2012.

In Colorado, the U.S. Forest Service planned to take advantage of the snow to burn piles of dead trees on federal land. Areas in the Texas Panhandle also had up to 8 inches of snow, and in south central Nebraska, Grand Island reported 10 inches of snow. And Arkansas saw a mix of precipitation -- a combination of hail, sleet and freezing rain in some place, 6 inches of snow in others.

Missouri Gov. Jay Nixon declared a state of emergency Thursday morning. All flights at Kansas City International Airport were canceled for Thursday night, and officials said they'd prepare to reopen Friday morning. More than 320 flights at Lambert Airport in St. Louis were canceled by Thursday afternoon. Traffic throughout the state was snarled by hundreds of accidents and vehicles in ditches.
