A somber holiday season reminder of loss, a Christmas tree decorated by the family of slain Draper police Sgt. Derek Johnson, has been put on display at the southwestern Salt Lake County community's City Hall.
Timothy T. Walker has been charged with first-degree felony aggravated murder, a death penalty offense, in the Sept. 1 ambush shooting of Johnson, 32. The officer, seeing Walker's car parked at an odd angle at 13200 S. Fort St., had stopped to help when Walker allegedly shot him inside his police car.
Prosecutors say Walker then turned a handgun on his girlfriend, Traci Vaillancourt, and then shot himself. Both Walker and Vaillancourt survived; Johnson, after driving a short distance and crashing into a tree, died at the scene.
