About 100 people gathered Monday evening at Seattle Center’s International Fountain to honor the victims of the deadly mass shooting at the Bite of Seattle festival that left three people dead and four others injured. Mayor Katie Wilson, Police Chief Shon Barnes, and community members attended the vigil, which focused on healing and supporting those affected by Sunday’s violence. Organizers and speakers called for an end to gun violence and urged the community to unite in the wake of the tragedy. While no one who spoke publicly said they personally knew the victims, several advocacy groups addressed the crowd. The vigil concluded with three minutes of silence, a prayer, and a community rendition of “This Little Light of Mine.”

The King County Medical Examiner’s Office identified the three people killed as Junior Cee Niko Semo, 19; Carlos Israel Sanchez Villalba, 44; and Ashley Whitehead, 56. Semo died from multiple gunshot wounds, while Sanchez Villalba died from a gunshot wound to the torso and Whitehead died at a hospital after suffering a gunshot wound to the pelvis. A GoFundMe campaign describes Whitehead as someone who loved life, art, and family, noting she was attending the festival with her daughter and future son-in-law when the shooting began.

Seattle police said they believe the shooting was gang-related and that investigators now believe Semo was one of at least two people who exchanged gunfire. A 15-year-old boy remains in custody on suspicion of first-degree assault and firearms violations, though no one has been formally arrested for investigation of homicide. Court documents released Monday allege three people were involved in a gunfight that broke out in the middle of the festival. Detectives are continuing to identify and locate a third person believed to have been involved.

The gathering came hours after city and police leaders held a second news conference to provide updates on the investigation and respond to criticism over the flow of information following the shooting. Wilson confirmed investigators are reviewing Seattle Center surveillance footage, although no cameras were positioned where the shooting occurred. She said officials are being deliberate about the information they release as the investigation continues. When asked whether police believe there is an ongoing threat to the public while another person remains outstanding, Wilson declined to answer. Assistant Police Chief Nicole Powell also declined to say whether recovered firearms had been reported stolen or linked to previous crimes.

Barnes acknowledged concerns about the department’s communication following the shooting and said Seattle police are working to improve how information is shared during major incidents. Seattle Center has since reopened to the public, and city officials said another community vigil is being planned for Wednesday, though additional details have not yet been announced.
