A West Valley man charged with beating his wife to death was bound over to district court Wednesday and ordered to stand trial on the charges.

Gary Lee Mabe, 38, is charged with second-degree murder in the Dec. 5 slaying of his wife, Carol Mabe, 45. Prosecutors say he has confessed to the killing but has not told them why he did it.On Dec. 5, a co-worker discovered the severely beaten body of Carol Mabe lying on the floor of her cubicle at Timesaver Industrial, 1515 S. Pioneer Road (2350 West). Officers told the Deseret News it was one of the worst beatings they had ever seen.

Police originally speculated that she had been killed by a burglar because a nearby cubicle was ransacked and her purse had been dumped. Later, however, detectives determined that nothing had been taken and theorized the assailant made the mess to make it appear as if someone had been there to burglarize the business.

The defendant said he had dropped his wife off at work early that morning and helped her with some janitorial tasks before he left for his job. He denied any knowledge of her death until he spoke with detectives Jan. 7. During a videotaped interview, Mabe confessed to the slaying, saying he struck his wife in the head with a metal bar and a pipe wrench, court documents state.

Salt Lake Police Detective John Johnson said Gary Mabe told him he hit his wife with an 18-inch pipe and then washed it off in a sink before hiding it in a pile of other pipes. When he returned, he heard his wife breathing and went to his car to retrieve a pipe wrench, which he used to beat her again.

Mabe will be arraigned before 3rd District Judge Kenneth Rigtrup on Feb. 25.
