Rockford, Wash. (AP) — Multiple ambulances and a Lifeflight helicopter were dispatched to a high school south of Spokane following reports of a shooting Wednesday morning.

KHQ Spokane is reporting that at least one person is dead, three more are injured and that a suspect has been detained.

The shooting was reported at Freeman High School in Rockford. Annie Baxter, whose two daughters attend Freeman Middle School across the street from the high school, told The Spokesman-Review that children were running into buildings when she pulled up to the school area about 10:15 a.m.

She says classes were about to begin because it's a "late start" day.

All schools in the Spokane district were placed on lockdown as a precautionary measure.
