Jennifer Crumbley found guilty of manslaughter after son goes on school killing spree in US

A jury has convicted a mother of involuntary manslaughter after her son shot four students dead — making her the first parent in the US to be held responsible for a child carrying out a mass school attack.

Michigan prosecutors said that Jennifer Crumbley had a duty under state law to prevent her son, who was 15 at the time of the killings in 2021, 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 11 hours of deliberations.

Jennifer 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 Craig Shilling, the father of victim Justin Shilling, and the family of Madisyn Baldwin.

“Thank you,” a man whispered to her.

Jennifer and James Crumbley were the first parents in the US to be charged in a mass school shooting committed by their child. James Crumbley faces trial in March.

“The cries have been heard and I feel this verdict is gonna echo throughout every household in the country,” Mr Shilling said.

“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.”

A gag order by the judge prevented McDonald and defence attorney Shannon Smith from speaking to reporters.

On the morning of November 30, 2021, school staff members were concerned about a violent drawing of a gun, bullet and a wounded man, accompanied by desperate phrases, on Ethan’s maths assignment.

His parents were called to the school for a brief meeting but they did not take their son 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 9mm his father had bought just four days earlier. Jennifer had taken her son to a shooting range that same weekend.

“You’re the last adult to have possession of that gun,” assistant prosecutor Marc Keast said while cross-examining the mother last week.

“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.”

Jennifer replied: “Yes, he did.”

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.

Jennifer 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.

The words with the drawing that prompted a counselor to call the Crumbleys to the school said: “The thoughts won’t stop. Help me. The world is dead. My life is useless.”

Prosecutors introduced evidence that Ethan Crumbley 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.

The jury of six men and six women included people who own guns or grew up with them in their home. The jurors said they could put their opinions about guns aside and serve fairly.

Jennifer will get credit for about two and a half 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.
