SAN FRANCISCO, July 2 (Xinhua) -- A three-year-old girl Monday died from stabbing injuries she received from an attack on Saturday night when she was having her own birthday party, police of the U.S. northwest state of Idaho said.
The police said they will not release her name until additional notifications have been made.
Among the other eight victims, one child has been released from the hospital and seven remained hospitalized for serious or critical injuries, the police said.
Thirty-year-old Timmy Kinner attacked with a knife at an apartment complex for refugee families, and stabbed nine people including six children who were celebrating the birthday for the three-year-old girl in Boise, capital city of Idaho state, about 840 km south of Seattle on the U.S. west coast.
Kinner has been booked into the Ada County Jail on nine counts of Aggravated Battery and six counts of Injury to Child.
The Boise Police said an investigation into Kinner was still ongoing, and that Kinner has an extensive criminal history spanning several states. He has spent time in prison.
They noted that the initial evidence does not suggest the attack was a "hate crime."
Kinner, a resident of Los Angels, is not a refugee but he had stayed at the flat complex for some time until he was asked to leave last Friday.
He came back the next evening and committed the attack on the party-goers, according to Boise police.
