A handgun was recovered from the suspect, undersheriff says
The three killed at Oxford High School are believed to be students, Oakland County Undersheriff Michael G. McCabe said at a news conference. One of those shot is believed to be a teacher.
The suspect was identified as a 15-year-old boy who is a sophomore at the school, McCabe said.
Calls for an active shooter came in around 12:51 p.m. ET.
“We received over 100 911 calls to our dispatch center,” McCabe said.
The suspect was apprehended without incident within five minutes of police arrival, McCabe said.
A handgun was recovered from the suspect, McCabe said. Authorities recovered multiple shell casings in the school and believe around 15-to-20 shots were fired.
“At this point in time, we believe he acted alone,” McCabe said.
The 15-year-old did not resist arrest, has invoked his right not to speak and is not telling law enforcement officers anything right now, McCabe said.
Officers were searching the school for possible additional victims.
All evacuated students were relocated to a nearby store for reunification with relatives.
Oxford Community School officials released a statement confirming the shooting and saying the “Oakland County Sheriff’s Department has secured the scene.”
Oxford is about 45 miles north of Detroit.
