A former New York prison worker who helped two murderers escape from a maximum-security lockup says she played along when they talked about their plan and never intended to pick them up.

In the second part of a two-part jailhouse interview aired Friday on NBC's "Today" show, Joyce Mitchell said she had no doubts Richard Matt and David Sweat would have killed her if she had met them with a car and a shotgun like they asked after they escaped June 6 from Clinton Correction Facility.

The pair went on the run for three weeks.

Matt was killed by a border agent June 26. Sweat was wounded by a state trooper two days later.

Mitchell has pleaded guilty to giving them tools. She faces up to seven years in prison.
