A judge denied a request from Ethan Crumbley, the student facing 24 charges in connection with the deadly Nov. 30 mass shooting at Oxford High School in Michigan, to be moved to a juvenile detention facility.

Conducting a hearing Monday over Zoom, District Judge Nancy Carniak called the 15-year-old, who is being held in the Oakland County Jail along with his parents, a "menace."

"I still feel strongly that his conduct could be a menace to other juveniles," Carniak said during the hearing. "I think his placement is appropriate in the adult facility."

Crumbley's lawyers argued that moving him to a juvenile facility would allow him to continue his education and described the shooting as an "isolated incident." They also expressed concerns that he was hearing adult noises next to him.

Crumbley wore a face mask and jumpsuit and scarcely spoke during the hearing. The next hearing will take place Jan. 7.

After the judge rejected the motion, prosecutor Marc Keast said he would ensure Crumbley was not within "sight or sound" of an adult in the facility.

Crumbley is accused of killing four students and injuring seven at the high school. Crumbley was charged as an adult and faces four counts of first-degree murder, one count of terrorism causing death, seven counts of assault with the intent to kill, and 12 counts of possession of a firearm in the commission of a felony. If convicted, he could face life behind bars.
