A 15-year-old arrested after Seattle’s Bite of Seattle food festival shooting was armed with a ghost gun, police said, and investigators say the weapon had an extended magazine.

Quick Take

Seattle police said the teen was detained after the shooting and was tied to firearms and assault allegations.
Chief Shon Barnes said the recovered weapon was a 9 mm Polymer80 ghost gun with an extended 33-round magazine.
Police said investigators found two other weapons and 14 shell casings at the scene.
Reporting also says police believed at least three shooters were involved, including a 19-year-old who died there.

What Police Said Happened

Police said gunfire broke out at the crowded festival near the Space Needle and left three people dead and four others wounded. Seattle police later said they detained a 15-year-old in connection with the shooting and booked him for firearms violations and first-degree assault. Reports said the teen was in juvenile detention while the case moved through the courts.

The strongest public claim is the one police repeated most clearly: the teen had a ghost gun at the scene. Chief Barnes said the weapon was a Polymer80 9 mm gun with an extended magazine, and reporters said investigators also recovered two other weapons and 14 shell casings from two calibers. That is the detail that gave the story its sharp edge from the start.

The Weapon At The Center Of The Case

The phrase “ghost gun” matters because it points to a privately made firearm that lacks a serial number and is hard to trace. In this case, police described the gun as a 9 mm Polymer80 weapon with a 33-round extended magazine. That detail turned a chaotic shooting into a bigger public fight over untraceable guns, youth violence, and how quickly dangerous weapons can spread through a crowd.

Police also said the scene involved more than one shooter. Reporting cited police and court material saying investigators believed at least three shooters were involved: the 15-year-old, a 19-year-old who died at the scene, and at least one unknown suspect. That is an important point, because the event was not presented as a simple one-gun case. It was described as an exchange of gunfire.

What Is Clear, And What Still Matters

The public record is strongest on possession and scene recovery. It is less final on the exact shot-by-shot role of the teen.

The sources say police believed he was shooting when he surrendered, but the material provided does not include a completed forensic report showing which gun fired which rounds. That gap matters in any fast-moving shooting case, especially when juvenile records are limited.

Even so, the basic outline is not in dispute. A teenager was taken into custody after a deadly festival shootout, police said he had a ghost gun with an extended magazine, and investigators found more weapons at the scene. The case now sits at the point where early police claims meet court process, evidence testing, and the slower work of proof.
