Teen suspect in custody, another dead after Seattle food festival shooting: Officials

There may be a third possible suspect in Sunday's shooting, officials said.

One suspect is in custody and another is dead following a gunfight at the Bite of Seattle food festival, where shots were fired into a crowd, officials said Monday.

One of the suspects, a 15-year-old boy, is in custody following Sunday's shooting, which left three people dead and several wounded, officials said.

Another -- a 19-year-old man believed to be an "associate" of the teen in custody -- was among those killed in the shooting, police said Monday.

There may be a third possible suspect, Seattle Mayor Katie Wilson said during a press briefing Monday.

Authorities were dispatched to the scene at the Seattle Center at about 6 p.m. Sunday.

"We now know that at least two people exchanged gunfire outside the Seattle Center Armory," Wilson said during a briefing Monday.

One is the teen in custody, and the second -- initially believed to be at-large -- has been identified as the 19-year-old deceased man, she said.

The 19-year-old man was detained at the same time as the 15-year-old, according to a court filing. The two "engaged in a gunfight with at least one other unknown suspect," during which the 15-year-old allegedly fired into a crowd, according to a probable cause statement filed in connection with the teen's detention hearing.

The 15-year-old was booked for investigation for firearms violations and first-degree assault, Wilson said at a news conference earlier Monday.

"We believe this teenager opened fire in the crowd, but details are still under investigation," Wilson said.

She added that no one has been arrested for investigation of homicide.

Seattle Assistant Police Chief Nicole Powell said Monday that the shooting is believed to be gang-related, and that there were "two groups firing" near the Armory during the food festival.

Police would not elaborate on whether the two identified suspects were working with each other or targeting each other, only saying they were associates and that it's an "active investigation."

At least seven people were caught in the crossfire, Wilson said.

The King County Medical Examiner's Office identified the two victims killed in the shooting as Ashley Whitehead, 56, and Carlos Israel Sanchez Villalba, 44, both of Seattle. They died from a gunshot wound to the pelvis and torso, respectively.

The office identified the 19-year-old suspect as Junior Cee Niko Semo, of Seattle, who died from multiple gunshot wounds.

Three injured victims -- a 2-year-old boy, a 23-year-old man and a 39-year-old woman -- were hospitalized and have since been discharged, authorities said.

A fourth injured victim, a 40-year-old woman, had minor injuries and declined to be taken to the hospital, according to officials.

Police said they are also investigating a potential fifth wounded victim. A 27-year-old man with a gunshot wound went to a hospital in satisfactory condition and police said they are working to determine if this person was hurt in the shooting.

The shooting erupted during Bite of Seattle, an annual festival with food vendors and live music held at the Seattle Center.

The 15-year-old will appear in court on Monday, Wilson said.
