OKLAHOMA CITY - An Oklahoma appeals court has upheld the life prison sentence of a man who was convicted of first-degree murder for the shooting death of a woman in Woodward County.

The Oklahoma Court of Criminal Appeals handed down the decision Thursday in the case of 59-year-old Richard Wayne Conway. A Woodward County jury found Conway guilty last year in the November 2009 shooting death of Cheryl Roberts.

Roberts was shot in the head while she was visiting Conway at his home on Nov. 3. Roberts died the next day.

Police say Conway told them that he became upset after he and Roberts argued, and then he shot her.

Conway's defense attorney, William H. Luker of the Oklahoma Indigent Defense System, said he had not seen the decision and could not comment.
