Special Officer Stephen Clark

End of Watch August 19, 1956

On August 19, 1956, Special Officer Stephen Clark was struck and killed by a stock car at the Bay Meadows Race Track while attempting to render aid following a crash on the track.

He was preparing to leave the track to direct traffic at the intersection of El Camino Real and Hillsdale Boulevard when two race cars had collided and crashed through the track fence at the south turn. A mass of spectators was attempting to reach the crash scene. Officer Clark instructed a fellow officer to keep the spectators from entering the track through the outside fence. As he attempted to cross the track to reach the inside fence he was struck by one of the stock cars.

Officer Clark had served as a volunteer reserve officer with the San Mateo Police Department for nine years. He was survived by his wife and brother.

Sergeant Gordon Joinville


End of Watch May 23, 1968


On May 23, 1968, Sergeant Gordon Joinville was shot and killed by Zachary Ford Lillard. He was the second San Mateo officer to have been killed in the line of duty.

Sergeant Joinville was 34-years-old and a 12-year police veteran at the time of his death. He is survived by his wife, Margaret, and two children.
Sergeant Joinville was investigating the possible manufacture of LSD. Sergeant Joinville, who was in an unmarked car, planned to follow the suspect’s car from Fifth Avenue and El Camino Real, to obtain the location of a drug lab. His investigation led him to his ill-fated meeting with Zachary Lillard. 

For reasons unknown, the suspect changed directions, and, according to witnesses, got out of his car and into the back seat of Sergeant Joinville's car. 

During Sergeant Joinville’s encounter with Lillard, there was a countywide alert because of an armed robbery and radio traffic was very heavy. Sergeant Joinville asked dispatch to run a computer check. He was asked to "stand by." That was Sergeant Joinville’s last radio transmission. Dispatch received a call from Bob Reed, a gas station owner, who advised that an officer had been shot at Fifth Avenue and Claremont Street. 
Sergeant Joinville had a piece of paper on his clipboard that had a name and license plate number written on it. An investigation led to the identification of Zachary Lillard as the suspect. Lilliard was also wanted for kidnapping, armed robbery, and assault. Through a vigorous manhunt, and a joint effort with the FBI, Zachary Lillard was located in San Francisco and taken into custody. The car he was driving at the time of the shooting, and the .45 cal weapon, were both recovered.

Zachary Lillard was convicted and sentenced to death; however, his death sentence was overturned by the courts. Zachary Lillard died, at the age of 69, while serving a life term sentence in the California State Prison system.

On October 5, 1968, the Joinville Swim Center was opened on Kehoe Avenue in Sergeant Joinville’s honor. He has been memorialized at the San Mateo County Hall of Justice, the Peace Officers Memorial in Sacramento, California, and the National Peace Officers Memorial in Washington DC.
