WASHINGTON (AP) — The Supreme Court won't overturn a death sentence for a man convicted of killing his ex-girlfriend and her infant daughter in Oklahoma.

The high court on Monday refused to hear an appeal from Raymond Eugene Johnson. Johnson was convicted of two counts of first-degree murder by a Tulsa County jury in 2009 in the June 2007 deaths of Brooke Whitaker, 24, and her 7-month-old daughter, Kya Whitaker. Prosecutors said Johnson beat Brooke Whitaker in the head with a hammer, set her on fire and left her and the baby to burn in their gasoline-doused home.

Oklahoma courts have refused to stop his execution, and the high court now also has refused to intervene.
