The suspected shooter at a Michigan high school has been identified as 15-year-old Ethan Crumbley, according to officials.
Crumbley will face charges including a count of terrorism causing death, four counts of first degree murder, seven counts of assault with intent to commit murder and 12 counts of possession of a firearm in commission of a felony, Oakland County prosecutor Karen McDonald said on Wednesday at a press conference.
McDonald added that she intended to charge Crumbley as an adult.
"This is unspeakable. We send our kids to school. We think that they're going to be safe, so the only thing that I can do as the prosecutor is ensure that I will do everything I can to prosecute this case and pursue justice for these victims but also to speak out and say that we need better gun laws," McDonald said.
Crumbley is suspected of killing four students and injuring seven other people in a shooting at Oxford High School on Tuesday. He was a sophomore at the school.
The victims in the shooting included 17-year-old Justin Shilling, who died Wednesday, as well as 14-year-old Hana St. Juliana, 17-year-old Madisyn Baldwin and 16-year-old Tate Myre, all of whom died Tuesday.
The prosecutor said there was no reason to be concerned about Crumbley's mental stability at this time, adding that officers' "response was executed perfectly," but the four student deaths indicated a need for more gun control.
She went on to say that she could not comment on Crumbley's potential motive at this time, but referenced a "mountain" of evidence in the case.
