SEATTLE -- Police have shot and wounded a man sought in the Halloween night killing of Seattle Police Officer Timothy Brenton, just as a massive memorial service for the officer drew to a close.

Tukwila police spokesman Mike Murphy said the shooting occurred as Seattle Police detectives pursued a tip at an apartment complex in the Seattle suburb. Television footage showed dozens of cruisers surrounding the building, while some officers examined a car that, though covered by a tarp, resembled the profile of an old Datsun seen nearby when the officer was killed.

Murphy said the man fled when approached by detectives outside the apartment building, but he was quickly boxed in. Three detectives opened fire when the man drew a handgun.

Two potential witnesses were also detained for questioning.

The Seattle Times quoted Interim Seattle Police Chief John Diaz as saying the person of interest was 41 and had been shot in the head.
