CUMBERLAND, Md. (AP) — A state prison inmate has been found mentally incompetent to stand trial for the 2013 beating death of his cellmate at the maximum-security Western Correctional Institution near Cumberland.

Thirty-six-year-old Darnell Thompson had a competency hearing Tuesday in Cumberland. He is charged with first-degree murder in the slaying of 29-year-old Jason Wallace.

Wallace was found unconscious in his cell during an inmate recreational period. Prosecutors say a state police detective who interviewed Thompson questioned his competency. The state’s attorney’s office requested a psychological evaluation, which concluded Thompson was incompetent.

He’ll receive treatment and have another review in 12 months.
