Crumbley, 15, is facing four counts of first-degree murder, one count of terrorism and seven counts of assault with intent to kill.
He is set to appear in court around 1 p.m. as attorneys prepare for a probable cause hearing next week, according to Fox 2 Detroit.
His parents, Jennifer and James Crumbley, are facing their own charges of involuntary manslaughter for not doing enough to sufficiently stop the teen from allegedly carrying out the attack.
The Nov. 30 slaughter at Oxford High School rocked suburban Detroit, as the community still grieves the deaths of Tate Myre, Hana St. Juliana, Madisyn Baldwin and Justin Shilling.
Crumbley’s parents bought the 9mm semi-automatic handgun their son allegedly used in the shootings just days before, prosecutors allege. The day of the shooting, his parents met with school administrators over a “disturbing” drawing the teen made of murders and guns but refused to take him out of school. The shooting happened just hours later.
Lawyers for a Michigan high school student injured in the shooting have accused the district of destroying relevant case evidence, according to recent court filings.
Crumbley is being held without bail and his parents are both being held on $500,000 bail. The two appeared to flee after being slapped with the charges and were arrested in Detroit following a manhunt.
The parents hired their own lawyer for their case, but the 15-year-old is being separately represented by a court-appointed lawyer.
