Parents of the Michigan high school shooting suspect pleaded not guilty to involuntary manslaughter charges on Saturday (Dec. 4). James and Jennifer Crumbley, parents of Ethan Crumbley, are accused of giving their 15-year-old son the gun he allegedly used to kill four people at the school as an early Christmas present.

According to prosecutors, shortly after James purchased the gun on Nov. 26, Ethan posted a picture of it on Instagram, writing, “Just got my new beauty today. SIG SAUER 9mm.”

His mother Jennifer also posted about the gun on social media, calling it “his new Christmas present.” Jennifer also took Ethan to the shooting range the weekend before the deadly school shooting, authorities say.

Defense attorneys for Jennifer and James have denied they supplied their son with the weapon and claim it was “locked” up. The two parents were charged with four counts of involuntary manslaughter on Friday (Dec. 3) and were supposed to be arraigned that afternoon. The couple said they intended to turn themselves in, but police discovered them “hiding” and “very distressed” in a warehouse in Detroit on Saturday morning, Detroit Police Chief James White said.

That afternoon, a judge in Michigan’s Oakland County set James and Jennifer’s bond at $500,000.

Ethan, who is accused of premeditating the shooting at his Oxford High School, was charged on Wednesday (Dec. 1) with four counts of first-degree murder, terrorism, seven counts of assault with intent to murder and 12 counts of possession of a firearm in the commission of a felony. He will be tried as an adult and, if convicted, faces life in prison.

“Charging this person as an adult is necessary to achieve justice and protect the public,” Oakland County Prosecutor Karen McDonald said Wednesday, one day after the deadly shooting. “I’m committed to seeking justice for the victims of the Oxford High School shooting and all Oakland County kids who face violence.”
