Jennifer Crumbley, the mother of the teenager who killed four people at a Michigan high school in 2021, took the stand in her manslaughter trial Thursday and testified it was her husband’s responsibility to store their son’s gun safely. She detailed the text message she received from her son, Ethan Crumbley, moments before the shooting. Both parents have pleaded not guilty to four charges of involuntary manslaughter. #CNN #News #EthanCrumbley #JenniferCrumbley #MichiganSchoolShooting
