David Sweat, New York Prison Escapee, Pleads Guilty to All Charges

The convicted murderer who escaped from a New York prison has pleaded guilty to all charges related to his time on the run.

One of two convicts who broke out of a New York prison pleaded guilty Friday to all charges related to his escape.

David Sweat spent 22 days on the run after a brazen breakout from the maximum-security Dannemora prison on June 6 with a fellow inmate, Richard Matt.

Matt was shot and killed by border patrol agents on June 26, and Sweat was caught two days later.

Sweat has been in solitary confinement at Five Points Correctional Facility in Romulus, New York since his capture, according to NBC affiliate WNYT in Albany.

He pleaded guilty Friday to two felony counts of first-degree escape and a felony count of promoting prison contraband for possessing hacksaw blades, the station said.

A prison seamstress has also pleaded guilty for her role in the jailbreak. Joyce Mitchell smuggled a drill bit and hacksaws to the inmates, according to authorities. The inmates then used the parts to cut holes in their cells and hack through underground steam pipes, which led them to a manhole out of which they popped out.

Mitchell pleaded guilty to a count of promoting prison contraband and was sentenced to between 2 years, 4 months in prison to up to seven years in prison. Last week, a judge ordered her to pay nearly $80,000 in restitution for damage to the prison.

Days after Sweat was captured, New York Gov. Andrew Cuomo said the two escapees had planned to go to Mexico — but had to improvise when Mitchell, their getaway driver, got cold feet.

"The plan was to head to Mexico, which would have been aided by Joyce Mitchell's vehicle," Cuomo said in June. "Then they would go live happily ever after — which was a fairy tale that I wasn't read as a child."

Mitchell, 51, had gotten involved romantically with Matt, sources told NBC News.

"She thought it was love," a source said in June.
