The semiautomatic gun used in the shooting at a Michigan high school was purchased by the suspect’s father on Nov. 26, four days before Tuesday’s shooting.
Officials were not releasing the name of the suspect because he had not been charged as an adult. The boy’s parents were not allowing him to talk to police.
The firearm was a 9-millimeter Sig Sauer pistol, and it had seven remaining rounds loaded in the gun when the suspect was arrested, Oakland County Sheriff Michael Bouchard said at a news conference on Tuesday night.
The sheriff said the gun had 15-round magazines. Law enforcement officials found two, but believed the father bought three.
Sheriff Bouchard said that officials did not know if there were other firearms in the suspect’s home, adding that was part of the investigation.
He confirmed that photos of a firearm, posted by the suspect on social media, appeared to be the same gun used in the shooting.
