A former coworker of Jennifer Crumbley, the mother of the Oxford High School shooting suspect Ethan Crumbley, testified that Jennifer Crumbley was having an affair around the time of the fatal shooting. The witness testified Jennifer Crumbley would leave during work hours to meet up with a man in the parking lot of Costco across the street from her office. Prosecutors are using the testimony to argue the Crumbleys, who were both allegedly having affairs, were too busy with their own lives to worry about what was going on with their son.
