The Oakland County prosecutor has identified the Oxford High School student who opened fire on his classmates as Ethan Crumbley and announced two-dozen charges against him, including terrorism and first-degree murder.
Karen McDonald said she would charge the 15-year-old sophomore as an adult in a Wednesday afternoon news conference. He faces life in prison if convicted.
"Any other option could put all of us at risk of this person, because he could be released," she said. "My job is to protect people in the community from crimes and that's what I intend to do."
The charges for the Tuesday shooting spree that killed four and wounded seven include:
terrorism causing death, one count
first-degree murder, four counts
assault with intent to murder, seven counts
posession of a firerarm in commission of a felony, 12 counts
At a video arraignment, Judge Nancy Carniak of 52nd District Court in Rochester Hills ruled Crumbley be held with no bond and be moved from Children's Village to Oakland County Jail, Fox 2 News reports.
Crumbley's parents may also face charges, McDonald said. The gun he used in the massacre was purchased by his father several days earlier.

Few additional specifics were provided, with McDonald saying she didn't want to compromise the investigation. Questions she declined to answer included whether the victims were targeted, if Crumbley took the gun without permission, if he or his parents have criminal backgrounds, and whether he threatened the attack in advance on social media.
A search warrant was executed at Crumbley's home and investigators continue to sift through a "mountain of evidence," McDonald said.
Information about the evidence seized was shared during Crumbley's video arraignment Wednesday afternoon, according to The New York Times:
Authorities told a judge that investigators had recovered two separate videos from the suspect’s cellphone, which were made the night before the incident. He talked about shooting and killing students the next day at Oxford High.
A journal in his backpack also detailed his desire to shoot up the school, authorities said.
Sheriff Mike Bouchard says Crumbley's parents had a face-to-face meeting with school officials roughly three hours before the shooting to discuss their son's behavior in the classroom, The Times' coverage adds.
Sheriff Bouchard said the suspect had also met with school officials about concerning behavior on Monday, the day before the shooting. He declined to specify the nature of that behavior, but said law enforcement agencies had not been notified.
The sheriff said the district had no record that the suspect had been bullied at school, and he did not believe specific students were targeted
