Five days after escaping from prison, a Tennessee inmate emerged from a field on Sunday, weathered and mosquito- and tick-bitten, and surrendered to law enforcement, officials said.

The inmate, Curtis Ray Watson, was captured on Sunday roughly 10 miles from the prison, the West Tennessee State Penitentiary, in Henning, Tenn., which is about an hour’s drive northeast of Memphis. Officials said he had sexually assaulted and killed a veteran prison executive and then fled on a tractor on Wednesday.

Mr. Watson looked “relieved to be over with his run,” David Rausch, the director of the Tennessee Bureau of Investigation , said at a news conference on Sunday. “He knew he wasn’t getting away because of the number of law enforcement that was present.”

Just before 11 a.m., Mr. Watson, with his hands raised, knelt down as Ashley Bird, a correctional officer, and Jessica Brown, a probation/parole officer, took him into custody, officials said.
