The windchill. And thats where we find our clayton sandell. Reporter good morning, ginger. Overnight here in denver, the low temperature record was smashed. The new record, minus 14 degrees.

At least 23 states, from california to michigan, being assaulted by one of the coldest air masses in decades. Temperatures in some areas expected to drop 30 to 50 degrees in as little as 12 hours. I can feel the truck kind of sliding. Reporter treacherous roads in the twin cities, attacking drivers. Highways littered with icy spinouts. Oh. Were going to hit. Were going to hit. Oh. Reporter teams of snowplows marching out in full force. And so many vehicles there, struggling to break free of nearly half a foot of snow. Here in colorado, sub zero windchills. And in parts, up to a foot of snow. On the frigid streets of denver, the Salvation Army is helping Homeless People find shelter. When you get cold snaps like this, its very dangerous. Reporter and 25mileperhour winds kicking up icy waves along lake superior. Making it look more like an ocean than a lake. And, ginger, in honor of your first day, we decided why not show off some of our favorite tv cold weather demonstrations. So, here you go. In about ten minutes outside, we made ice cubes. And of course, we have the hammer made from a frozen banana. And my personal favorite, the frozen tshirt. The bottom line is, for millions of people are going to be seeing wicked cold temperatures in the next few days. Ginger . Clayton, thank you. Of course i love that stuff. In about eight months, denver, youll be doing the fried egg on a sidewalk. Lets talk about what happens before then. Its the ice were concerned about. And it starts tonight through early tomorrow. Its more than a halfinch in little rock. This gets on trees. It gets on power lines and you have major problems. You could see up to an inch adding up into parts of western kentucky. This could put out power. Were going to be talking about this storm through the week. Beginning of the weekend, really. On top of it, its minimal snow. But its snow. Were not into real winter yet. But it feels like it. I have more coming up. Today, were going to be 60 in new york. Were just showing off. Thank you, ginger. We get the latest on that truck packed with Dangerous Nuclear material, stolen in mexico. It was found abandoned with some of the Radioactive Material missing. No sign, yet, of the gunmen who stole it. Abcs chief justice correspondent Pierre Thomas has been tracking the story from the start. He joins us now. Good morning, pierre. Reporter good morning, george. Its been an incredible 24 hours with that lethal material stolen. And now, apparently recovered. The thieves are still on the run. But they are now in grave danger. Mexican authorities discovered the stolen truck and the highly Radioactive Material, cobalt 60, abandoned in the countryside, not far from mexico city. It culminated in the huge search and manhunt that spanned six states and mexico, and has some officials worried about the prospects of the stolen Radioactive Material being used to make a socalled dirty bomb. Its a lot of radioactivity. You could get a lethal dose in just a few minutes from being exposed to this source. Reporter Authorities Say the container carrying the cobalt was found less than a mile from the truck. The thieves opened the container and left the lethal material on the ground, apparently all of it recovered. Police are actively checking mexican hospitals for evidence of anyone suffering from radiation exposure. The device was stolen on its way from tijuana en route to a radioactive waste Storage Facility not far from mexico city. Monday, two armed men confronted the truck driver at this remote gas station. The gunmen took off with the truck and its cargo. Authorities dont know who they are or if they even knew the Radioactive Material was onboard. Mexican officials suspect the theft was a carjacking and that the thiefs were more interested in stealing the truck than the device. Its still an extremely dangerous situation. The area where the material was found is surrounded. And the recovery and cleanup may take days to complete. George . Pierre, thanks very much. Lets get todays other top stories from josh. Were going to begin with breaking if yous here. An American Teaching in an International School in benghazi, libya. Was shot and killed while he was out jogging. The Associated Press said the teacher was from texas and taut chemistry. Todays attack not far from last weeks attack. Theres no claim for the responsibility of the shooting. Well have updates as news becomes available. And a massive cyberattack, targeting websites we just every day. Hackers have stolen the user names and passwords for nearly 2 million accounts in total at facebook, google, twitter, yahoo and linkedin. Perhaps youve heard of a few of them. The hackers installed a virus on computers around the world to capture login information and route that information to servers they had set up. Also targeted, the Payroll Service company adp. Meaning some workers paychecks may have been exposed as well. So, what can you do . You can update your antivirus software. And change your password. The most common password of hacked accounts is 123456. Cant imagine why. Thousands of workers at fast food chains such as mcdonalds and burger king are walking off the job today, demanding pay raises. But the question this morning, how much would an increase in their pay end up costing you, the consumer. Abcs Rebecca Jarvis here in new york, with some insight there. Good morning to you, rebecca. Reporter hi, josh. Good morning to you. A typical fast food worker in america makes about 9 an hour. But even those who support their efforts to increase their wages say that that would increase, if they were to increase those wages, that would increase the price of fast food by 20 if these workers were to get what they want. Protests across the country this morning. Scenes like this in new york, expected in 100 cities, including chicago, denver, houston and l. A. , with Fast Food Restaurant employees walking out of work and on to picket lines. Until we lift workers up and give them wages they can live off of, there wont be a true recovery from the greatest recession since the depression. Reporter protesters say a typical cashier or cook makes less than 19,000 a year. About 1,000 below the poverty line for a family of three. They want the minimum wage more than doubled. From 7. 25 an hour to 15. Now, the president is joining the conversation. We know that there are airport workers and fast food workers and nurse assistants and retail salespeople who work their tails off. And are living at or barely above poverty. Reporter the National Association of restaurants are fighting back. Saying dramatic increases in starting wage will increase prices for restaurant meals and lead to fewer jobs created. And one of the reasons youre seeing scenes like this all across the country is that restaurants have been one of the few places to show the biggest signs of job growth since the great recession. So, more and more american families, josh, are having to rely on those jobs to get by. Rebecca jarvis in new york. Thank you for that. Meanwhile a desperate rescue effort resume this morning to save dozens of whales stranded in the Florida Everglades after swimming to shallow water. You see some of them there. Two beached whales there. Wildlife workers have not been able to coax the surviving whales back to open water. Well have updates throughout the morning here. And finally, this could be victorias real secret. If youll forgive me. A former employee at the lingerie chain said that workers there are trained to treat men and women differently. Tell only women about special sales promotions. The thinking is, and stay with me, its rather scientific. Men who are always awkward in that store will pay anything just to get what they came for and get out of that store as quickly as possible. While the stores will not comment, i can offer a focus group of one when i say, yep. Yep. Scientific. Scientific. Science, robin. Thats it. Thank you, josh. Now, to the latest on the Sexual Assault allegations against Jameis Winston, the Florida State football star, who is a Heisman Trophy candidate. Prosecutors say they will announce today whether they will bring charges. Abcs matt gutman is here and has the latest. Good morning, matt. Reporter good morning, robin. This announcement could change the lives of both Jameis Winston and his still anonymous young accuser. If he is charged, winstons College Football career could be over. If hes exonerated, it could end with a heisman and a national championship. Its not a pass on the gridiron but a press conference that could determine Jameis Winstons fate later today. The state attorney on the case will announce whether or not the Florida State seminoles heisman hopeful will face charges of Sexual Assault from a fellow student, just a day after winston was named conference player of the year. That state attorney telling reporters wednesday, we think weve exhausted all investigative tools. On tuesday, he said his investigation was not based on a football schedule or anyone elses calendar. A reference not only to the seminoles shot of a National Title but the 19yearold quarterbacks campaign for the Heisman Trophy, which goes to the best College Football player, nine days from now. I pressured him to hurry the investigation. I know the media has the questions. And i know he has a desire to get this off his plate. Reporter that decision on charges coming as winstons Florida State seminoles secured the top rank in College Football for the first time in 13 years this week. If Jameis Winston were to be charged with a felony, he would not be eligible to play. Reporter according to the police report, the accuser was raped in december of 2012. It took her a month to identify winston. But when she did, her Attorney Says detectives warned that tallahassee was a big football town. And that the alleged victim needed to think long and hard about a complaint because her life would be made miserable. Winstons attorney acknowledging the two had sex but insist it was consensual. He would like to put closure to this. So he can move forward. Reporter most legal analysts weve spoken to agree that if winston were to face charges, there wouldnt be a press conference. The state attorney would likely have arrested him by now. And despite allegations, Jameis Winston is still the favorite to win the heisman. Okay, matt. Thank you. Going to bring in abcs dan abrams right now. A lot has been made of the timing. Prosecutors have maintained that has nothing to do with their actions. They just got this case a few weeks ago. This has been a longtime investigation. But from their perspective, just the prosecutors, theyve only been formally investigating this for a number of weeks. Theyre saying, look. Back off, to some degree. All of you suggesting that this is somehow related to the heisman or to the championship game, et cetera. This is, in their view, a very typical investigation in a highprofile case with difficult facts, where they need to take a little bit of time. But theyve now come forward. And i give them that credit to that degree. I dont believe that the timing here is somehow connected to the championship game or the heisman voting, et cetera. The length of the investigation that youre talking about and we heard in matts piece, that the alleged assault took place december of last year. January, she identified winston. February, it was ruled an inactive case but not closed. Is that unusual . And does what is it the victim or winston how are they affected by the length of this . It is unusual. But remember, lets distinguish the Police Department from the d. A. s office, the attorney generals office. You can criticize the Police Department and say they should have done things that they didnt do. They shouldnt have done things that they did do, et cetera. Now, its in the hands of the prosecutors, which is almost a separate investigation. Have we been given any indication what might happen today . Most people watching this think there wont be charges. But well see. Thanks, guys. Well turn to the frantic search under way in central idaho for the missing plane carrying a Silicon Valley executive and his family. The plane took off sunday night from oregon but never made it to its destination in montana. Authorities detected a faint signal from the planes emergency beacon. And today, the search enters its fourth day. Abcs Neal Karlinsky has the story. Reporter new video by search and rescue teams show how cold and rugged it is where dale smiths plane vanished sunday.

Reporter smith was flying home from thanksgiving with his son, daughter and their significant others, headed from oregon to butte, montana, when he radioed in that he was having engine trouble near yellow pine, idaho. Emergency officials have put five planes and two helicopters in the air with infrared radar, looking for signs of life in the rugged terrain. Ground teams have been searching, as well. But with temperatures dropping below zero, it is not easygoing, and relatives are scared. We dont know if theyve got food. We dont know how injured they are.

Reporter this, as walkers reallife girlfriend appeared in public for the First Time Since the accident. Appearing somber outside walkers family home. The l. A. Coroner has ruled the cause of death was traumatic and thermal injuries. The car, driven by walkers friend, race car driver roger rodas, who also died, ran into a fixed object. Their deaths have been ruled accidental. But toxicology tests wont be back for up to two months. The fast furious stars sudden death has cast a shadow over the 2. 3 billion movie franchise that rocketed walker to fame.
