A teenager has pleaded guilty to terrorism and murder charges in connection to the killing of four classmates and wounding several other people in a school shooting last November.
Ethan Crumbley, now 16, was accused of opening fire on fellow students in Oxford High School in a Detroit suburb on November 30 2021.
The gun was a Christmas gift his father purchased days before the massacre, authorities said.
In a court notice earlier this year lawyers for Crumbley said he would mount an insanity defense but those plans appear to have changed, according to Oakland County Chief Assistant Prosecutor David Williams.
"We can confirm that the shooter is expected to plead guilty to all 24 charges, including terrorism and the prosecutor has notified the victims," Williams said in a statement on Friday.
"There have been no plea deals, no reductions and no sentencing agreements."
Crumbley was charged with one count of terrorism causing death, four counts of first-degree murder, seven counts of assault with intent to murder and 12 counts of possession of a firearm in the commission of a felony.
The four people who died where Madisyn Baldwin, 17; Tate Myre, 16; Hana St. Juliana, 14, and Justin Shilling, 17. All died at the scene except for Justin Shilling who died en-route to the hospital.
Three lawyers representing Crumbley, who was a 15-year-old at the time of the killings, did not immediately return calls seeking comment.
Crumbley appeared in court 8:30 am local time (12.30 GMT). Among the dozens of charges is a count of terrorism causing death and four counts of premeditated murder by a juvenile, according to the prosecutor.
Four students were killed in the rampage and six other students and a teacher were wounded.
Crumbley's parents, James and Jennifer Crumbley, also face involuntary manslaughter charges connected to the shooting.
In that case, Rochester District Court Judge Julie Nicholson said evidence showed they purchased their son a gun despite signs that he was a "troubled young man."
The case appears to be the first in the United States in which the parents of a teenage school shooter have been charged with crimes attributed to their child. They have pleaded not guilty.
Four days before the shooting, Ethan Crumbley accompanied his father to a gun shop, where James Crumbley bought a 9mm handgun, prosecutors said.
Crumbley is said to have attended a parent-teacher meeting just three hours before the killings to discuss his "behaviour".
Other students claim the teen gunman was bullied at the school, which is 40 miles north of Detroit.
But cops say there are no records of Crumbley being picked on.
Prosecutors report that a journal detailing his desires to shoot students was found in his backpack, according to the MailOnline.
Crumbley was uninjured and arrested by officers who arrived at the scene within two to three minutes of the first 911 call reporting the shooting.
Tate has been described as a “standout” football player at who died from his wounds on the way to the hospital in the back of a patrol car.
Myre, a talented footballer for the school team, was described by a fellow sportsman as a beloved athlete in the area.
Matt Johnson, 17, told The New York Post : “He was a standout player. He inspired many people and was loved by many people."
