PONTIAC, Mich. (Michigan News Source) – The 16-year-old gunman who opened fire at Oxford High School last November pled guilty on Monday morning to all 24 charges he faced.

Ethan Crumbley, who was 15 at the time of the shooting, faced one count of terrorism and four counts of first-degree murder charges in the shooting that left four students dead. Six other students and a teacher were hurt in the shooting. In addition, Crumbley faced a variety of other charges.

Some of the victims’ relatives were in the courtroom Monday as Crumbley answered “yes” to questions posed to him by the court.

Prosecutors said a deal had not been made to secure the guilty plea. First-degree murder typically brings an automatic life sentence in Michigan. However, teenagers who are convicted of the charge can have a hearing in which their attorneys can request a shorter term with the possibility of parole.

Crumbley will be sentenced on February 9.
