Both men were serving life without parole sentences, officials said. UPDATE: Calvin Adams and Jeffrey Grinder were captured in New York state on June 2, 2009, after a state trooper tried to pull them over for speeding in the same car they used to escape Arkansas prison. The car crashed and the two were captured as they tried to get away on foot.
The two men were caught on video putting on the uniforms in the prison library shortly after the 6 p.m. head count at the facility. About 20 minutes later, they walked out of the prison during a staff shift change.
It was three hours later before they two men were missed. Officials are investigating if the two escapees had help.
Car Waiting for Them
"Someone should have laid eyes on them. That's one of the things we're looking at: How exactly did they get out without someone challenging them?" corrections department spokeswoman Dina Tyler told reporters.
The escapees drove away in a maroon or burgundy, 4-door sedan that had been left for them, investigators said. Both men have family connections in Arkansas and out of state.
Adams was convicted of capital murder in 1995 and Grinder was convicted of murder in 2004.
