OXFORD, Mich. (FOX 2) - The gun used to kill four people Tuesday at Oxford High School was purchased by the suspect's father four days before the shooting, Oakland County Sheriff Michael Bouchard said.
A 15-year-old sophomore used that gun bought on Nov. 26 to fatally shoot three students and injure eight others, including a teacher.
When deputies stopped the teen and took the gun from him, it was loaded and still had seven rounds in it.
"We believe he came out of a bathroom with a weapon in hand. Deputies took (the gun) from him he was walking down the hall," Bouchard said. "That interrupted what could have led to several more victims. The way I see it is, there were seven more victims in that gun."
Authorities searched the suspected shooter's home Tuesday evening and seized evidence, including what appeared to be several long guns.
