On the morning of November 29, 2009, Sergeant Mark Joseph Renninger, 39, was fatally shot in an ambush at a coffee shop in Parkland, Washington. Renninger was a 13-year veteran of law enforcement and was at the shop with three Lakewood Police Department colleagues—Officer Tina DeLong-Griswold, Officer Greg Richards, and Officer Ronald Owens—catching up on paperwork before their shifts when a lone gunman entered and opened fire.

The attacker, later identified as Maurice Clemmons, killed Sergeant Renninger and Officer DeLong-Griswold instantly at their table. A struggle followed with the remaining officers; Officer Owens was also fatally shot and Officer Richards managed to wound Clemmons before being killed. Clemmons fled, triggering a nationwide two-day manhunt.

Clemmons was located in the early morning of December 1, 2009, in South Seattle when a Seattle officer investigating a stolen vehicle confronted him. Clemmons was fatally shot after refusing commands and appearing to reach for a weapon; investigators later found he was armed with a handgun taken from one of the slain officers. Several relatives and associates were arrested and charged with rendering criminal assistance for helping Clemmons evade capture.

Did anyone in the area see the suspect enter or leave the coffee shop that morning?
