Mountain View detectives investigating new information in cold case homicide

Mountain View detectives are investigating new information in a decades old cold case that left one man dead. 

On April 27, 2000, 20-year-old Michael Duayne Wallace was shot and killed while at a minimum-security work furlough center, located at 590 East Middlefield Road. The building has since been demolished.

Wallace was standing in a hallway shortly after 10 p.m. and had turned to face the entrance of the building when he was shot in the chest. He was on clean-up duty at the time, mopping the hallway and talking with another inmate when the incident unfolded.

At the center, Wallace was both an inmate and an employee, serving as a crew chief who made sure other inmates checked in and out while working when they either entered or left the facility. He had been scheduled for release in May 2000 when he was shot and killed. 

Despite an intense investigation, detectives at the time could not find a motive for the shooting, or a viable suspect.   

The shooting by an outside assailant is the first of its kind for a county detention facility.

For years, the case remained open, but unsolved.  We are asking that anyone who may have any additional information on this incident to contact our Crimes Against Persons Unit Det. Andrew Wong at  

Media inquiries can be sent to PIO Katie Nelson at
