Six of the victims were ages 3-12, and the others were adults, Police Chief William Bones said. Four of the victims suffered life-threatening injuries, he said, and some injuries will be “life-altering.”
Bones said officers were called to the Wylie Street Station Apartments on Saturday night and quickly found the suspect not far from the site of the attack. Timmy Kinner, 30, was arrested without further incident, police said.
Kinner, of Los Angeles, was booked into the Ada County Jail on nine counts of aggravated battery and six counts of injury to a child.
“Last night’s horrific attack does not represent Boise,” Mayor Dave Bieter said Sunday. “Please join me in praying for the injured and their families. We must come together to condemn this vile act.”
The victims, who included members of the refugee community, were found in the parking lot and inside the complex. Bones said investigators were trying to determine why the suspect targeted them.
“It’s a community within our community,” Bones said. “We had children from different continents sitting at a small child’s birthday party.”
Kinner, who has a criminal record, has not been cooperative with investigators, Bones said.
Kinner is not a refugee but had been a temporary resident of the apartments until he was asked to leave Friday. Bones did not say why Kinner was kicked out, but he echoed Bieter’s assurances that the crime in no way reflects on the attitudes of the city’s 220,000 people in a metropolitan area dubbed “Treasure Valley.”
