The mother of the Michigan school shooter, Jennifer Crumbley, took the stand in her trial for involuntary manslaughter. The jury heard that her son blamed his parents for not getting him help before the 2021 attack that killed four students. Evidence presented included portions of the teenager’s journal, where he wrote about his mental problems and his parents’ refusal to listen to him. Jennifer and her husband, James Crumbley, are accused of making a gun accessible at home and neglecting their son’s mental health needs. Their son, Ethan Crumbley, pleaded guilty and is serving a life prison sentence.
