WEST JORDAN, Utah -- The man charged with the murder of a Draper City Police officer faced a judge Tuesday.

Timothy Troy Walker, 35, is accused of shooting and killing Draper City Police Sgt. Derek Johnson on Sept. 1. 

Police said Walker also shot Traci Vaillancourt, 34, then turned the gun on himself around the same time he allegedly opened fire on Johnson. Vaillancourt is now facing two counts of obstruction of justice for giving police different accounts of the incident. She is also appeared in court Tuesday.

Walker has officially been charged with criminal homicide, aggravated murder and attempted homicide. He was set to appear in court in September, but medical conditions kept him in the hospital.

Officers said Walker has been writing notes to medical staff indicating he didn't want to be resuscitated and he expressed remorse for what had happened.

Walker and Vaillancourt are expected to be back in court on Dec. 3.
