The parents of a Michigan teenager accused of murdering four fellow high school students were founding hiding in a commercial building in Detroit, Michigan, after missing their arraignment hearing earlier on Friday.

In a new conference early Saturday morning, Detroit police said James and Jennifer Crumbley were taken into custody. Both have been charged with four counts of involuntary manslaughter in connection with the campus mass shooting.

Police Chief James White said the couple had not broken into the building where they were arrested, but had been let in by somebody.

“Yes, in fact, they were aided and we’re looking into that portion of the investigation and that part is very active right now,” White said.

The couple’s 15-year-old son, Ethan Crumbley, is being held without bail and has been charged as adult on suspicion of carrying out the deadliest US school shooting of 2021 on Tuesday at Oxford High School, about 40 miles (60 km) north of Detroit.

Crumbley’s parents were expected to appear for a Friday afternoon arraignment but stopped responding to calls from their attorneys, according to Oakland County Undersheriff Mike McCabe, prompting a search by the Sheriff’s Fugitive Apprehension Team.
