Watch live: Mother of Oxford school shooter Ethan Crumbley takes the stand in manslaughter trial

For the first time, the mother of Oxford High School mass shooter Ethan Crumbley spoke on her own behalf Thursday, taking the stand in her historic criminal trial, telling jurors that she never believed her son was a threat to others nor saw any signs that he needed mental health treatment. She also addressed one of the key allegations in this case: that she refused to bring her son home from school after being summoned over a violent drawing he had made.
