An inmate at the East Arkansas Regional Unit in Lee County was found dead in his cell Thursday morning, the state Department of Corrections said in a news release.
Stephen Keirsey, 53, appeared to have committed suicide, the department said. It said the Arkansas State Police is investigating, and the Corrections Department is conducting an internal inquiry into the death.
Keirsey has been serving a life sentence out of White County for first-degree murder. He was arrested in October 2010 in the killing of 26-year-old Kaitlyn Moudy, who had been found shot to death near Romance, located about 50 miles north of Little Rock.
Keirsey was sentenced in September 2011.
