Michigan school shooter’s mother found guilty of involuntary manslaughter

Mother of shooter, who killed four students in 2021, was accused of gross negligence for failing to tell school the family possessed guns

Jennifer Crumbley, the Michigan mother accused of involuntary manslaughter when she failed to inform her 15-year-old son’s high school that the family possessed guns shortly before he went to campus and fatally shot four students and injured six, including a teacher, was found guilty of all charges Tuesday afternoon.

The verdict came after jurors on Monday began deliberations in a case that could shape the criminal liability of parents of underage mass shooters. The maximum penalty for involuntary manslaughter under Michigan law is 15 years in prison.
