Richard Matt, one of the two killers who escaped an upstate New York prison three weeks ago, was shot and killed Friday, two senior New York state officials told NBC News. (Tweet this)
The whereabouts of the second escapee, David Sweat, were not immediately known.
Matt was shot south of the town of Malone, about 40 miles from the prison, Sheriff Kevin Mulverhill of Franklin County told MSNBC.
Video shot by a bystander captured a swarm of law enforcement vehicles, and an officer could be heard saying, "We have one guy down."
Matt and Sweat have confounded authorities since June 6, when they were reported missing after sawing through the walls of their cells, shimmying through the works of the building and popping out of a nearby manhole to freedom.
A prison seamstress, Joyce Mitchell, has been charged with helping the two escape. Authorities have said she was romanced by Matt and was originally supposed to be the getaway driver. They have said she smuggled tools to the men inside packages of raw meat.
She is accused of bringing hacksaw blades, chisels, a punch and a screwdriver bit into the prison five weeks before the escape. Clinton County District Attorney Andrew Wylie said she also provided glasses with lights attached, presumably to be used in the tunnels.
Wylie said Mitchell planned to meet the men at around midnight on the night of the escape and pick them up, but got cold feet.
This week authorities charged a second prison worker, Gene Palmer, and said he delivered the packages.
