Six inmates, including four murderers, cut through a gate and escaped from Ohio's only privately run prison Saturday afternoon. Police had captured one of the inmates before nightfall.

The six broke out of the Northeast Ohio Correctional Center and apparently split up after escaping, police said.Officers searching nearby woods with dog teams found three white prison uniforms the inmates were wearing. The inmates had to clear razor wire to escape, and searchers found one of the uniforms stained with blood.

The inmate who was captured, convicted armed robber Jamal Heath, surrendered about 15 miles southeast of the prison after a resident called authorities.

Heath was injured while escaping and was taken to a hospital. He had changed out of his uniform, said Robert Kane, chief of detectives for the Youngstown police.

"When I asked him where he got the clothes, he just smiled," Kane said.

Some inmates may have created a distraction that caused officers to leave their positions in the recreation yard, officials said.

The prison has been plagued with problems since it opened in May 1997.
