A total of four officers had been shot and killed in Pierce County over the past 30 years. That toll doubled Sunday morning when a cold-blooded assassin entered a coffee shop and executed four Lakeland, Wash., police officers. The deaths of Sgt. Mark Renninger, 39, and Officers Ronald Owens, 37, Tina Griswold, 40, and Greg Richards, 42, will leave the Lakeland Police Department with permanent scars. But they weren’t just officers. Three fathers and one mother were killed. Nine children are grieving the loss of parents.
