Hours before a 2021 mass school shooting in Michigan, the mother of a teenager who killed four students said she was worried that he was "going to do something dumb,” a man who had a close relationship with her testified Wednesday. Brian Meloche said Jennifer Crumbley explained to him that she had to go to Oxford High School after a teacher discovered a violent drawing on Ethan Crumbley's math assignment the morning of the tragedy. “Something with Ethan. (She) was worried he was going to do something dumb,” Meloche said. Meloche, who was having an extramarital affair with Jennifer Crumbley at the time, said he knew through social media posts that the parents had recently purchased a gun for the boy. “I asked where the firearm was. ... If something was going to occur it would produce immediate irreparable damage,” Meloche testified.
