CHANDLER, Okla. — The Oklahoma Court of Criminal Appeals has upheld the life prison sentence of a 26-year-old man convicted of first-degree murder in the stabbing death of a Texas man.

The court ruled Tuesday in the case of Keven Jimmy Ray Hallmark, who was found guilty last year following a non-jury trial before Lincoln County District Judge Cynthia Ashwood in the June 7, 2013, stabbing death of 41-year-old Sam Brock of Odessa, Texas.

Brock died in a motel room in Chandler after he was beaten, suffocated and his throat was cut. Affidavits in the case say Brock’s body was found face down and a large fixed-blade knife was found near the body.

A co-defendant, 25-year-old Dominique Gill, was also convicted of first-degree murder and sentenced to life in prison.
