Mother of Michigan School Shooter Jennifer Crumbley Guilty of Involuntary Manslaughter

It's a landmark ruling, the first of its kind ... the mother of Michigan high school shooter Ethan Crumbley has been found guilty of involuntary manslaughter ... and she could be sentenced to 15 years in prison.

Jennifer Crumbley was convicted of being grossly negligent by not stopping her son Ethan Crumbley from killing 4 students at Oxford High School in November, 2021.

The jury reached the unanimous verdict on the second day of deliberations.

Never before has a parent been criminally charged with a child who committed a mass shooting. Jennifer's husband, James, is also facing manslaughter charges and will stand trial next month. He's the one who purchased the gun.

Jennifer testified in her trial James was responsible for hiding the gun their son used in the shooting.

Jennifer also testified she knew her son was struggling but had no idea he was capable of committing a mass shooting. She never put her son Ethan in therapy and said if she had it to do over again she would have done nothing differently.
