Seattle police looking for third shooting suspect

In the US, police in Seattle said on Monday there were at least three suspects involved in a food festival shooting near Seattle's Space Needle over the weekend, and that one of them was among those killed in the violence.

In a document filed in juvenile court in Seattle, where a 15-year-old arrested in the case did not turn up for an initial appearance Monday, police said they believe there were at least three shooters: the 15-year-old; an acquaintance who died at the scene; and "at least one other unknown suspect," the document said.

It was not immediately clear why the teen did not appear in court.

A judge ordered the teen 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.

The gunfire erupted around 6 p.m. Sunday in the waning hours of the Bite of Seattle, leaving three people dead and at least four others injured.

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.
