David Sweat shot and captured alive after New York manhunt

Malone, New York (CNN)A massive, more-than-three-week manhunt for David Sweat ended Sunday as it began, with the escaped murderer in custody.

Authorities said a New York State Police sergeant -- identified as Jay Cook -- spotted Sweat, and after Sweat ran, the sergeant gave chase.

"At some point, running across a field, he realized that Sweat was going to make it to a tree line, and possibly could have disappeared, and he fired two shots," New York State Police Superintendent Joseph A. D'Amico told reporters.

Sweat, who was unarmed, was hit twice in the torso.

A photo exclusively obtained by CNN shows Sweat in custody moments after his capture. He appears bloodied and was wearing a camouflage outfit, not prison garb.

He was taken into custody in the town of Constable, in upstate New York, very close to the Canadian border.

"I can only assume he was going for the border, that he was that close," D'Amico said.

Sweat was captured about 16 miles north of the location where fellow escapee Richard Matt was killed last week. The officer was alone when he shot Sweat.

Sweat was transported to the Alice Hyde Medical Center in Malone, an officer at the hospital told CNN. He was later moved to Albany Medical Center, where he was listed in critical condition, according to Dennis McKenna, medical director there.

Emergency, trauma, intensive care, radiology and vascular surgery specialists are involved in his care, McKenna said.

No law enforcement officers were injured during Sweat's apprehension.

"The nightmare is finally over," said New York Gov. Andrew Cuomo. "We wish it didn't happen in the first place. But if you have to have it happen, this is how you want it to end."
