Seattle police say 15-year-old arrested in connection with festival shooting had a ghost gun

SEATTLE (AP) — The 15-year-old arrested after a shootout at a food festival near Seattle’s Space Needle over the weekend was armed with a ghost gun with an extended magazine, police said Tuesday.

Police Chief Shon Barnes told a news conference that the weapon was a 9 mm gun from Polymer80 — a now-defunct company that was once a leading manufacturer of ghost gun parts.

Investigators also recovered two other weapons and 14 shell casings that had been fired by weapons of two different calibers, he said.

The shooting in the waning hours of the three-day Bite of Seattle festival left three people dead, including a 19-year-old gunman, and at least four people injured, including a toddler. Authorities say they believe the violence was gang-related, and they are reviewing any available surveillance video and interviewing victims and witnesses in an effort to identify others who may have been involved.

A potential eighth person potentially injured by gunfire checked themself into a hospital after the shooting, but checked out before investigators could conduct an interview, Barnes said. Legal obstacles have prevented them from obtaining the patient’s identity, he added.

Ghost guns are privately made — often homemade — firearms that lack serial numbers used to trace them. They are often purchased without a background check. Law enforcement officials say ghost guns, including those made with 3D printers, have increasingly been used in violent crimes across the U.S.

The weapon the 15-year-old had been shooting when he surrendered to police was equipped with an extended 33-round magazine, Barnes said. The magazine still had 19 rounds in it.

At the scene Sunday night, police also recovered a 9 mm handgun that they do not believe was used in the shooting.

And on Monday, as food vendors were allowed to return to the area to clean up and collect their equipment, a third weapon was discovered: a Glock 45 model 9 mm with a switch allowing it to fire fully automatically, Barnes said. Police believe that gun was fired during the shooting. It had an extended 40-round magazine, with 21 rounds remaining in it.

In a document filed in juvenile court in Seattle on Monday, police said they believed there were at least three shooters: the 15-year-old, an acquaintance who died at the scene and “at least one other unknown suspect.” Authorities had earlier said they believed there were two.

The King County Medical Examiner’s Office on Monday identified the dead as Carlos Israel Sanchez Villalba, 44; Ashley Whitehead, 56; and Junior Cee Niko Semo, 19.

Villalba was a husband and father of three known for his kindness and willingness to help others, according to a GoFundMe campaign launched Monday to help his family with funeral expenses. He died from a gunshot wound to his torso, while Whitehead died from a gunshot to her pelvis and Semo died from multiple gunshot wounds, according to the medical examiner’s office.

Whitehead had just moved to Washington from Alabama a year ago and was enjoying the festival with one of her adult daughters when she was shot, her cousin Michelle Whitehead told The Associated Press. She was taken to the hospital and died in surgery, she said.

Ashley Whitehead adored her two adult daughters, and also loved nature and arts and crafts, her cousin said.

“I would consider her just a free spirit. She had the best sense of humor, the best gorgeous smile,” she said.

During a vigil Monday night at the center, Michelle Whitehead stood among dozens of others with a sign that said “Whitehead Strong” as the group held a moment of silence and raised up flashlights on their phones to honor those that had been killed. Candles and flowers were arranged around them.

The four wounded included a 2-year-old boy, two men, ages 23 and 27, and a woman, 39, all of whom were discharged, a hospital spokesperson said.

One of the victims was walking a bicycle when struck, the court document said. The toddler was with his mother.
