ST. LOUIS (AP) — The Missouri Supreme Court has set a May execution date for a man convicted of killing a deputy and two other people 13 years ago.  The court on Thursday issued a warrant of execution for 66-year-old Earl Forrest. His execution on May 11th would be the first this year.

Forrest was convicted of killing Harriett Smith, Michael Wells and Dent County Deputy JoAnn Barnes in December 2002.

Smith was killed at her Salem home in a drug dispute, and Wells was visiting her. Barnes died in a shootout when officers went to Forrest’s home to investigate the killings.

Missouri executed 10 men in 2014 and six last year, but the pace is expected to slow because most of the remaining death row inmates still have court appeals pending.
