Seattle shooting: Ghost gun found on 15-year-old suspect at Bite of Seattle festival

Seattle officials said that the teen suspect may have been using a ghost gun and that they want to hear from one person who was treated for gunshot wounds.

A loaded “ghost gun” was recovered at the scene of a deadly Seattle shooting over the weekend, police said Tuesday as they continue to search for a possible third suspect.

The weapon was found on a 15-year-old who is suspected of being one of the shooters Sunday at the Bite of Seattle food festival, where three people were killed and four were injured. The teen was taken into custody and remains in juvenile detention, according to police.

Ghost guns are firearms that can be assembled at home from parts purchased online. The parts are often obtained without background checks and do not have serial numbers, which would make the guns traceable.

Police found a polymer 89 mm firearm with an extended magazine. It had a 33-round capacity, and 19 rounds remained in the magazine when investigators retrieved it, Police Chief Shon Barnes said at a news conference Tuesday afternoon.
