PONTIAC, Mich.—A Michigan jury convicted a school shooter’s mother of involuntary manslaughter Tuesday in the killings of four students in 2021, making her the first parent in the United States to be held responsible for a child carrying out a school attack.
Prosecutors say Jennifer Crumbley had a duty under state law to prevent her son, who was 15 at the time, from harming others. She was accused of failing to secure a gun and ammunition at home and failing to get help to support Ethan Crumbley’s mental health.
The four guilty verdicts—one for each student slain at Oxford High School—were returned after roughly 11 hours of deliberations.
Ms. Crumbley, 45, looked down and shook her head slightly as each juror was polled after the verdicts were read.
On her way out of the courtroom, prosecutor Karen McDonald hugged relatives of victims Justin Shilling and Madisyn Baldwin.
Ms. Jennifer and Mr. James Crumbley were the first parents in the United States to be charged in a school shooting committed by their child. Mr. Crumbley faces trial in March.
“I feel it’s necessary, and I’m happy with the verdict. It’s still a sad situation to be in. It’s gotta stop. It’s an accountability, and this is what we’ve been asking for for a long time now,” Justin’s father Craig Shilling said outside the courtroom.
A gag order by the judge prevented Ms. McDonald and defense attorney Shannon Smith from speaking to reporters.
On the morning of Nov. 30, 2021, school staff members were concerned about a violent drawing of a gun, bullet, and wounded man, accompanied by desperate phrases, on Ethan’s math assignment. His parents were called to the school for a meeting, but they didn’t take the boy home.
A few hours later, Ethan pulled a handgun from his backpack and shot 10 students and a teacher. No one had checked the backpack.
The gun was the Sig Sauer 9 mm his father had purchased with him just four days earlier. Ms. Crumbley had taken her son to a shooting range that same weekend.
Outside the courthouse, the jury forewoman, who declined to give her name, said jurors were influenced by evidence that Ms. Crumbley was the last adult to possess the gun. That “really hammered it home,” she told reporters.
Indeed, the jury saw images of Ms. Crumbley leaving the shooting range with the gun in a box.
“You saw your son shoot the last practice round before the [school] shooting on Nov. 30. You saw how he stood. … He knew how to use the gun,” assistant prosecutor Marc Keast said while cross-examining the mother last week.
“Yes, he did,” Ms. Crumbley replied.
In her closing argument Friday, Ms. McDonald said she filed the unprecedented charges because of the “unique, egregious” facts leading up to the shooting. School officials insisted they would not have agreed to keep Ethan on campus that day if the parents had shared information about the new gun.
The words with the disturbing drawing said: “The thoughts won’t stop. Help me. The world is dead. My life is useless.”
“He literally drew a picture of what he was going to do,” Ms. McDonald said. “It says, ‘Help me.’”
Besides 17-year-old Justin Shilling and 17-year old Madisyn Baldwin, Hana St. Juliana, 14, and Tate Myre, 16, were also killed. Seven people were wounded.
Ethan, now 17, pleaded guilty to murder and terrorism and is serving a life sentence.
Ms. Crumbley told jurors that it was her husband’s job to keep track of the gun. She also said she saw no signs of mental distress in her son.
“We would talk. We did a lot of things together,” she testified. “I trusted him, and I felt I had an open door. He could come to me about anything.”
In a journal found by police, Ethan wrote that his parents wouldn’t listen to his pleas for help.
“I have zero help for my mental problems and it’s causing me to shoot up the … school,” he wrote.
Prosecutors introduced evidence that Ethan texted his mother in spring 2021 about “demons” throwing bowls and other hallucinations. But she told the jury that it was “just Ethan messing around.”
“I have asked myself if I would have done anything differently. I wouldn’t have. I wish he would have killed us instead,” she testified.
Ms. Crumbley will get credit for roughly 2.5 years in the county jail when she returns to court for sentencing on April 9. The judge will set the minimum prison sentence, based on scoring guidelines and other factors.
It will be up to the Michigan parole board to determine how long she actually stays in prison. The maximum term for involuntary manslaughter is 15 years.
Prosecutors have not said if they will ask for consecutive sentences on the four convictions, which could mean a maximum of 60 years if Judge Cheryl Matthews agrees.
