MALONE, N.Y. (AP) — One of two convicted murderers who staged a brazen escape from an upstate maximum-security prison three weeks ago was shot and killed Friday in a gunbattle with law enforcement officers in a wooded area about 30 miles from the prison, and the other is on the run.

U.S. Sen. Charles Schumer, who was briefed by the U.S. Border Patrol and U.S. Marshals Service, said Richard Matt was fatally shot by a Border Patrol agent from Vermont. Officers are trucking in floodlights to where David Sweat is believed to be hiding, not far from where Matt was killed.

Schumer said searchers closed in on the pair after receiving a 911 call from a woman who heard a knock on her door early Friday in Malone, which is about 30 miles west of the Clinton Correctional Facility.

“She didn’t answer the door, but she called the police,” he said. “They brought the dogs, and they got a scent. They followed that scent and put out a lot of troops around the cabin. They came upon him and found him and killed him.”

Schumer said at least one of the prisoners was armed. State police said law enforcement spotted Matt at around 3:45 p.m.

The pair escaped early June 6 from the prison in Dannemora, near the Canadian border. Police have blocked off roads in the area as officers hunt for Sweat.

Gov. Andrew Cuomo scheduled a media briefing on the manhunt at 8:30 p.m. in Malone.

State Police Maj. Charles Guess said earlier Friday that the search area had shifted slightly northwest to Malone after investigators found evidence left behind by the escapees. Items were found Thursday at a cabin and Friday morning in a field, both in Malone, he said.

Matt and Sweat used power tools to saw through a steel cell wall and several steel steam pipes, bashed a hole through a 2-foot-thick brick wall, squirmed through pipes and emerged from a manhole outside the prison.

Sweat was serving a sentence of life without parole in the killing of a sheriff’s deputy in Broome County in 2002. Matt was serving 25 years to life for the killing and dismembering of his former boss. They were added to the U.S. Marshals Service’s 15 Most Wanted fugitives list two weeks after getting away.

The search for the escaped killers was initially concentrated around the prison and a rural community where search dogs had caught the scent of both men. The search had since been expanded to neighboring counties, and, while authorities said there was no evidence the men had gotten out of the general area, they conceded they could have been almost anywhere.

Vermont authorities became involved in the search early on after investigators got a tip that the inmates had talked about going there.

A pair of prison workers has been charged in connection with the inmates’ escape.

Prosecutors said Joyce Mitchell, a prison tailoring shop instructor who got close to the men while working with them, had agreed to be their getaway driver but backed out because she felt guilty for participating. Authorities also said Mitchell had discussed killing her husband, Lyle Mitchell, as part of the plot.

Joyce Mitchell pleaded not guilty June 15 to charges including felony promoting prison contraband, which authorities said included hacksaw blades and chisels.

Authorities said the men had filled their beds in their adjacent cells with clothes to make it appear they were sleeping when guards made overnight rounds. On a cut steam pipe, the prisoners left a taunting note containing a crude caricature of an Asian face and the words “Have a nice day.”

Clinton County District Attorney Andrew Wylie said the inmates apparently used tools stored by prison contractors, taking care to return them to their toolboxes after each night’s work.

On June 24, authorities charged Clinton correction officer Gene Palmer with promoting prison contraband, tampering with physical evidence and official misconduct. Officials said he gave the two prisoners the frozen hamburger meat Joyce Mitchell had used to hide the tools she smuggled to Sweat and Matt. Palmer’s attorney said he had no knowledge that the meat contained hacksaw blades, a bit and a screwdriver.

The escape was the first from Clinton Correctional’s maximum-security portion. In July 2003, two convicted murderers used tools from a carpentry shop at Elmira Correctional Facility to dig a hole in the roof of their cell and a rope of bedsheets to go over the wall. They were captured within three days.

Updated 4:45 p.m.: One of two convicted killers who staged a brazen escape from an upstate New York maximum-security prison and had been hunted for three weeks has been shot and killed.

An official with knowledge of the manhunt says Richard Matt was killed and David Sweat is still on the run. The official wasn’t authorized to talk about the development publicly and spoke to The Associated Press on Friday on the condition of anonymity.

Gov. Andrew Cuomo says Matt and Sweat used power tools to saw through a steel cell wall and several steel steam pipes, bashed a hole through a 2-foot-thick brick wall, squirmed through pipes and escaped early on June 6 from Clinton Correctional Facility in Dannemora, near the Canadian border.

Sweat was serving a sentence of life without parole in the killing of a sheriff’s deputy in Broome County in 2002. Matt was serving 25 years to life for the killing and dismembering of his former boss.

A prison guard and a prison tailor shop instructor have been accused of helping the inmates escape.

Richard Matt, one of the inmates who escaped from a New York prison, was shot by police Friday afternoon, according to several media reports.

Law enforcement authorities were searching in a remote area of Franklin County, N.Y.

The other escapee from Clinto Correctional Facility, David Sweat, was being pursued by law enforcement authorities.

This story will be updated.

Updated 4:30 p.m.: Police searching for two escaped inmates are converging on an area near the Canadian border where officers had concentrated their search, but the reason isn’t immediately clear.

There was no immediate word from state officials about the response Friday.

It comes as searchers on the trail of Richard Matt and David Sweat found new evidence left behind by the pair. The area police are converging on is south of Malone, about 30 miles west of Clinton Correctional Facility.

Hundreds of officers looking for Richard Matt and David Sweat shifted the focus of their search slightly northwest to woods and fields around Malone

The pair escaped June 6.

Updated 1:20 p.m.: Authorities say more evidence left behind by two escaped New York prisoners has been found in an area near the Canadian border where more than 1,100 law enforcement officers are concentrating their search.

State police Maj. Charles Guess says the items were found Thursday at a cabin and Friday morning in a field, both in the town of Malone, 30 miles northeast of the maximum-security prison David Sweat and Richard Matt broke out of June 6. Guess says the items have been sent to a forensic lab for testing.

He isn’t revealing details about the items but refers to them as “significant.”

Other evidence was found last weekend in a hunting cabin in the neighboring town of Bellmont.

Guess says the search effort is moving north toward the Canadian border.

Updated 9:45 a.m.: Police are again shifting the focus of their search for two convicted murderers who escaped from a maximum-security prison in northern New York three weeks ago.

Hundreds of law enforcement officers have spent most of the past week concentrating on a heavily wooded area 20 miles west of Clinton Correctional Facility, where David Sweat and Richard Matt broke out June 6. Authorities say DNA evidence confirmed the fugitives had been inside a hunting camp near the hamlet of Mountain View.

By Friday morning, fewer officers were around the hamlet while others were searching a few miles north in the town of Malone, near the Canadian border.

A small contingent of New York state troopers is stationed along power lines in the town, and motorists have to pass through a checkpoint.

Updated 9:15 a.m.: New York state prison officials say the corrections officer charged after the escape of two convicted murderers has been suspended without pay.

Gene Palmer’s suspension from his $72,644-a-year job comes after he was arrested Wednesday night on charges of promoting prison contraband, tampering with evidence and official misconduct.

Palmer has told investigators he provided paint, tools and prison catwalk access to Clinton Correctional Facility inmates Richard Matt and David Sweat, who escaped June 6. But the 57-year-old veteran guard says he had no idea they were planning to escape.

Before the charges came down, Palmer was suspended with pay from his job at the northern New York prison.

He is free on $25,000 bail.
