Update 4:45 p.m. Suspect in officer’s slaying shot by police in Tukwila

Hundreds of Seattle Police Department officers, members of the Seattle Honor Guard, Portland Honor Guard, law enforcement officials from several states – including Oregon and Montana – and the public gathered to honor fallen Officer Timothy Brenton in a memorial procession and service at Key Arena today.

Officer Brenton was killed on Saturday night, October 31, when he and a trainee were sitting in his patrol car in the 100 Block of 29th Avenue South. A vehicle pulled up next to them and fired multiple shots into the car. The student officer received only minor injuries.

The procession left the University of Washington at 9 a.m. this morning, shutting down streets throughout the city as the more than 1,000 vehicles made their way to Key Arena for the memorial service.

Streets throughout the city were blocked off to make way for the procession. The motorcycle officers were first to arrive at Key Arena.

The band marched after them.

Followed by the cavalry.

And then a motorcade of police vehicles.

The public memorial service begins at 1 p.m. at Key Arena. There is no formal procession planned for after the service, there still may be added congestion on the roads due to the blocked off streets, rerouted buses and sheer numbers of people in attendance.

Officer Brenton was 39 years old. During his career he served with the Hoquiam and La Conner police department, before spending the last nine years with the SPD. He is survived by his wife, Lisa, daughter, Kayleigh, 11, and son, Quinn, 8.

A fund has been set up for Officer Brenton’s family. Donations can be made at any Bank of America branch, just say you would like to contribute to the “Brenton Family Assistance Fund.”

A white flag with the Seattle Police Badge, Seattle Police emblem and Officer Brenton’s serial number is flying atop the Space Needle until tonight. Donated by the Space Needle Corporation, the 20 x 30 foot flag will be given to his family. See a picture at the PI Police Blog.
