JONESBORO, Ark. (AP) — A man who pleaded guilty to capital murder in the death of his estranged wife has died in the Craighead County jail a day before he was to be transferred to the state prison system, authorities said.
Marco Clark, 37, of Lake City died at a Jonesboro hospital where he was taken when he was found unconscious shortly after complaining to a jailer of stomach pains.
Rolland said the jailer saw Clark sweating heavily and went to get oxygen and a blood pressure monitor, then returned to find Clark collapsed in his cell.
Clark had pleaded guilty June 2 to capital murder in the 2019 death of Melinda Colburn near Lake City and was sentenced to life without parole.
Rolland said Clark was to be transferred to the state Department of Correction.
Clark’s body was sent to the state Crime Lab in Little Rock to determine the cause of death, Rolland said.
