Jennifer Crumbley Verdict: Oxford shooter's mom found guilty of involuntary manslaughter

Jennifer Crumbley has been found guilty of four counts of involuntary manslaughter by a jury following her trial in Oakland County court. The decision is a monumental one and the first of its kind in the U.S. Crumbley is the first parent of a mass shooter to be charged and convicted in connection with their child's crime. Four students who were enrolled at Oxford High School died following the shooting by Crumbley's then-15-year-old son.
