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 on Tuesday afternoon.
The verdict marked the first time a school shooter’s parent has been convicted of homicide in connection with the underlying violence. It came after jurors on Monday began deliberations in a case that could shape the future criminal liability of parents of underage mass shooters.
