1:17 'This is a tragedy': Seattle authorities respond to mass shooting at food festival – video At least three suspects involved in Bite of Seattle shooting, police say Court filing shows authorities believe there is at least one more shooter than the two previously thought Seattle authorities said on Monday there were at least three suspects involved in the deadly shooting at a food festival on Sunday evening near the Space Needle. One of them was among the three killed in the violence. A document filed in juvenile court on Monday revealed a suspect aged 15 was arrested and waived his initial court appearance. The filing also showed that police think there are at least three shooters rather than the two initially reported: the 15-year-old, an acquaintance who died at the scene and “at least one other unknown suspect”. Authorities did not release the name of the arrested suspect because he is a minor. A description of the other suspects was not immediately available. Nicole Powell, the Seattle police department’s assistant chief of investigations, told a news conference on Monday afternoon that investigators believe the shooting may have been gang-related, with two groups firing at each other. The deceased shooter was 19. A judge ordered the 15-year-old held in juvenile detention for investigation of firearms violations and first-degree assault. The King county prosecutor’s office said it expected to receive the case from Seattle police on Wednesday for a charging decision. Tyrone Davis, the assistant Seattle police chief, told reporters on Sunday night that investigators believed the two suspects were shooting at each other. Although one remained at large, Davis said there was no continuing threat to the public. The Seattle Center was hosting the Bite of Seattle food festival over the weekend. The annual three-day festival draws hundreds of food and retail vendors and performers to Seattle Center, a sprawling park in the shadow of the Space Needle. Many attendees rushed into campus buildings or ran from the park at the sound of the shots. 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, according to the medical examiner’s office. Four who were injured – including a two-year-old boy – were hospitalized. On Monday, the boy was in satisfactory condition, police said. The others – two men, ages 23 and 27, and a woman, 39 – were discharged, a hospital spokesperson said. The shootout was among more than 270 mass shootings in the US so far for the year as of Monday morning, according to the Gun Violence Archive .
