PROVO — A man accused of killing his supervisor at his Pleasant Grove workplace has been charged with capital aggravated murder.

Louis Darrell Kinyon, 49, American Fork, appeared Monday in a Provo courtroom to hear the charges against him.

Kinyon is also charged in Provo's 4th District Court with third-degree felony sex exploitation of a minor and aggravated assault.

Police say Kinyon, who worked at the Provo River Water Users Association for four years, was meeting on Feb. 2 with the victim, Kent Neil Griffith, 36, to discuss his future with the company. He had been suspended the week before.

"The whole disciplinary thing that started this involved his (Kinyon's) use of a company computer," Pleasant Grove Police Capt. Cody Cullimore said, referring to the sex exploitation charge. He would not give further details of the allegations.

Police say an angry Kinyon left the meeting and returned a short time later with a handgun. He chased co-workers before fatally shooting Griffith. Kinyon then walked into a rest room and shot himself.

Kinyon spent nearly a month in the hospital before being booked into the Utah County Jail on Feb. 27. He is being held without bail.
