Mother of Michigan school shooter found guilty of manslaughter

The mother of a shooter who killed four students at a high school in Oxford, Mich., in 2021 was found guilty Tuesday on all charges of involuntary manslaughter.

Jennifer Crumbley, 45, had pleaded not guilty to four involuntary manslaughter counts, and the jury found her guilty after 10 hours of deliberation, per CNN. 

Her son, Ethan Crumbley, was sentenced to life in prison in December after he pleaded guilty in 2022 to two dozen charges, including terrorism and first-degree murder. 

In addition to killing Tate Myre, 16, Hana St. Juliana, 14, Justin Shilling, 17, and Madisyn Baldwin, 17, Ethan Crumbley also wounded six students and a teacher. 

Jennifer Crumbly faces up to 15 years in prison for her role in the shooting. Prosecutors said she was "grossly negligent" in giving a gun to her son, who was 15 at the time, and not helping him obtain mental health treatment despite showing warning signs.
