Katie Couric Instagram – 🚨 Jennifer Crumbley was convicted on four counts of involuntary manslaughter, one for each student her son killed in Michigan’s deadliest school shooting. Her son, Ethan Crumbley, who was 15 at the time, used a pistol to kill Madisyn Baldwin, 17; Tate Myre, 16; Justin Shilling, 17; and Hana St. Juliana, 14. Seven other people were injured. The gun was a gift from his parents. She faces a maximum penalty of 15 years in prison after being convicted of all four counts. Ethan, who pleaded guilty to 24 charges including first-degree murder, was sentenced last year to life in prison without the possibility of parole. He did not testify in his mother’s trial. Ms. Crumbley’s husband, James Crumbley, 47, will be tried separately in March. Jennifer and James Crumbley are the first parents in the U.S. to be charged in a mass school shooting committed by their child.
