Iowa Gov. Tom Vilsack said he removed the warden of a prison where two inmates escaped last week by using a homemade grappling hook. The Iowa State Penitentiary warden, Ken Burger, will be reassigned and soon will retire, the governor said this week.

Vilsack said seven prison employees now have been disciplined over the escape of Joseph Legendre, 27, and Martin Moon, 34. He blamed the escape on a significant breach of security and said there had been no head count in the prison section where the two men worked.

The inmates used a rope fashioned from upholstery webbing and homemade grappling hook to scale a 30-foot wall at the prison in Fort Madison. Both men were recaptured late last week - one in Illinois and the other in Missouri.
