from nbc news world headquarters in new york this is "nbc nightly news" reporting tonight kate snow. good evening. and across far northern new york it's been another stressful day for people living with the fear that an armed escaped killer in the woods. david sweat is still on the run after his partner in crime, richard matt, was shot and killed by a u.s. can customs and border protection tactical team on friday. we're getting new details tonight about how that team tracked matt down and where the two men have been hiding. nbc's stephanie gosk has been covering the story since their brazen escape. stephanie, where does the search stand now? >> reporter: well they're hopefulful tonight kate. the search area is 22 miles.

there are helicopters, canine units searching the woods. we asked the county sheriff if he thinks they're getting close. he said today is the day. but then he added, he says that every day. one down one to go. but the relief that richard matt was shot and killed did not last long. there's still another killer on the loose. >> it will be better when they're both gone. >> reporter: david sweat is now on his own after a 911 call from a vacationer whose camper was hit by a gunshot. at that same minute bob said they were being interviewed by police after atlantic or bottles were out of place. >> he was outside. they said it's a gunshot. >> reporter: with when troopers went to investigate the cabin, they installed gun powder. matt, armed with a shot gun, was killed in the woods.

head to the border. there are places where it's easy to cross. residents say there are cameras on this road that border guards on the other side of the river keep an eye on. but they are still nervous. >> one is gone. the other, hopefully they will find him soon >> reporter: law enforcement has benefited from a few straight days of good weather. but that will change. torrential rain is in the forecast. it will considerably slow their search down. >> not helpful. stephanie, i think we all had a sense they were closing in on david sweat too. what happened? >> reporter: law enforcement thought they were traveling together. no one actually saw david sweat yesterday. a couple of things could have happened. they could have been in different places. the other option when they left that cabin, sweat is a lot younger than richard matt. he could have been that much faster slipping through their fingers and richard matt couldn't get away. kate? >> stephanie gosk in upstate new
