NYPD to AST

Alaska is the largest state in the U.S., which means Troopers have their work cut out for them when it comes to hunting down criminals on the loose. In the Mat-Su Valley, Troopers and K9s are tracking down a couple of thieves through the snowy backwoods. Meanwhile, a blaring horn has everyone perplexed — it's difficult to track the source of the noise and it could be a desperate call for help, so the Troopers split up to cover more ground. In Fairbanks, Troopers are also on the hunt, but this time for an armed and aggressive home intruder.
