SEATTLE - Seattle Police are receiving some new clues as they search for the person who shot and killed Officer Tim Brenton.
Wednesday night, a man was arrested in a Ballard bar. It was not immediately known if the case was connected to the shooting.
Among Seattle's police officers, the frustration that there hasn't been a quick arrest is clear. But now there's a new concern.
At least one violent street gang is now hinting at more violence and the target: Seattle Police.
Just blocks from the shooting scene they found gang graffiti – a violent threat against a specific Seattle Police detective.
The gang squad is chasing down those responsible and trying to stop any group from capitalizing on the shooting.
While no one is saying the graffiti is directly related to the murder of Officer Brenton, it is a sign of how tense things are on the streets right now.
The Seattle Times reported that investigators found a note threatening Seattle Police officers at the scene of a firebombing nine days before the shooting and that pipebombs were planted, raising the level of sophistication of the attack.
They could be connected.
Police would not reveal specifics of the evidence found at the Charles Street maintenance yard but did stress if there had been a threat, it would have been passed along to officers.
Meantime police say they believe they have the shooter's car on dash cam video from two or three different squad cars in the area of the shooting on Halloween night.
Today Officer Brenton's family came to the memorial at the crime scene.
Officer Brenton's father Boyd, a retired Seattle policeman, now prepares to bury the son who followed in his footsteps.
Late today the formal honor guard arrived at the spot where Officer Brenton was killed in cold blood.
The reward is now $105,000 for information that leads to the arrest for the murder of Officer Brenton. You can call in tips to 206-233-5000 or Crimestoppers at 800-222-TIPS.
There will be a special flag-raising ceremony at the Space Needle Thursday morning at 10 a.m. to honor Officer Brenton.
Friday there will be a procession and memorial service. About 1500 vehicles will leave the University of Washington at 9 a.m. and head to Key Arena. The procession is expected to last until noon and no other traffic will be allowed on the route. The memorial starts at 1 p.m. at Key Arena. KING 5 will carry it live.
