(CBS) — BOISE, Idaho — A man who had been asked to leave a Boise apartment complex returned the next day and stabbed children celebrating a 3-year-old girl’s birthday, authorities said Sunday. Five children, ages four to 12, and three adults were injured in the attack. Boise Police Chief William Bones said the victims are alive, although some are gravely injured.

A resident of the apartment complex where the stabbing took place had allowed 30-year-old Timmy Kinner to stay there a short time, but asked him to leave Friday because of his behavior, Bones said. Kinner returned Saturday, when the girl was having her party a few doors down from where he had stayed, according to police.

Kinner, of Los Angeles, was charged with nine counts of aggravated battery and six counts of injury to a child, CBS affiliate KBOI-TV reports.
