Constable Gustave Adolph Koch

Gustave Adolph Koch

Constable Gus Koch was one of five deputies killed as a result of a powder magazine explosion.

Constable Koch had served with the Alameda County Sheriff's Office for four years. He was survived by his father, three brothers, and two sisters.

Deputy Daniel Cameron, Constable Gustave Koch, Deputy John Lerri, Deputy Charles White, and Deputy George Woodsum were killed when a powder magazine containing a barricaded murder suspect exploded. The suspect was an employee of an explosives company and had murdered a coworker during a dispute over Chinese lottery tickets.

The suspect fled into the powder keg, which contained 5-tons of powder, and threatened to blow it up if anyone attempted to arrest him. The standoff continued overnight and into the morning until the suspect called to Deputy White and told him he was ready to come out.

As the other deputies approached the magazine it suddenly exploded, killing the five deputies, a female bystander, the suspect, and seriously injuring two other deputies.
