Roll of Honor
Incident
Sergeant Mark Renninger, Police Officer Tina DeLong-Griswold, Police Officer Greg Richards, and Police Officer Ronald Owens were shot and killed in an ambush-style attack while sitting in a coffee shop in Parkland.
All four officers had just finished a call and went to the coffee shop to complete paperwork. Sergeant Renninger, Officer Owens, and Officer DeLong-Griswold were seated at a table, and Officer Richards was in line waiting to order coffee. The suspect entered the shop, walked directly over to the table where the three officers were sitting, drew a 9 mm handgun, and shot Officer DeLong-Griswold, killing her. The suspect then shot Sergeant Renninger, killing him.
After shooting the two officers, the suspect’s weapon jammed, and he became involved in a physical fight with Officer Owens. During the struggle, the suspect drew a second weapon, a .38 caliber revolver, and shot and killed Officer Owens. Officer Richards, hearing the shots, moved toward the suspect and became involved in a physical fight with him. Officer Richards was able to shoot the suspect once in the torso before the suspect was able to gain control of his weapon. The suspect then shot Officer Richards, killing him.
The suspect fled the location, prompting a two-day manhunt. He was shot and killed by a Seattle police officer after the officer observed him near a stolen car. The officer attempted to take the suspect into custody, but the suspect refused to follow commands and attempted to flee, prompting the officer to fatally shoot him.
Sergeant Renninger had 13 years of law enforcement experience, five with the Lakewood Police Department and eight with the Tukwila Police Department.

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.

Thank you for your service to the Lakewood community. Thank you for your service before it. Gone but never to be forgotten.
Rest easy, brother.
