An Ogden man has died from a gunshot wound he suffered in a double shooting that also claimed the life of a woman, police said.

Richard Ben Castillo died Tuesday of a brain hemorrhage at the University of Utah Health Sciences Center, where he had been hospitalized since the March 10 shooting, said hospital spokesman John Dwan.

Castillo underwent surgery Monday night as doctors attempted to stop bleeding in his brain, Dwan said.

Ogden detectives say they have not ruled out theories that the deaths of Castillo, 40, and Jolene Mary Oney, 28, Ogden, could have been a murder-suicide or that the pair were shot by a third person.

Oney was found dead in a bedroom of Castillo's home, which was decorated with satanic symbols and horror movie paraphernalia, police said. Officers found Castillo, incoherent, lying between the front room and a bedroom. Both had been shot in the right temple.

Two guns were found in the home, and police said Oney may have been dead as many as 12 hours before she and Castillo were discovered by his sister.

Detective Scott Conley questioned Castillo shortly after he was admitted to the hospital, but police have not disclosed what was said.
