The killing of four Lakewood police officers appears to be the worst attack on law-enforcement officers in state history.

Sunday’s fatal shooting of four Lakewood police officers appears to be the worst attack on law-enforcement officers in state history.

Previous deadly attacks on officers in Washington include:

• In 1906, Marshal Michael Glover, Kennewick Police Officer Joseph Holzheyand Deputy Marshal Forest Perry were shot and killed as a posse attempted to arrest several burglary suspects at a hobo camp.

• In 1921, three members of the Seattle Police Department were killed, two slain by a gunman first spotted on Broadway, and the third shot later in the day when he spotted the suspect in downtown Seattle.

• In 1935, two Seattle police officers were killed responding to a burglary just north of the city limits.

• On Easter in 1949, in what became known as the Easter Massacre in Pullman, the Whitman County sheriff, a deputy, and a Pullman police officer were killed by a gunman.

• In 1987, Island County Deputy Sheriff’s Deputy William Heffernan and Deputy John Saxerud were shot and killed by a man they had arrested for drunken driving. The man pulled out a gun and shot the deputies as the three men were in the jail’s processing area.
