(NewsNation) — The murder trial of an Illinois sheriff’s deputy accused of killing Sonya Massey, a Black woman shot in her home last year after calling police for help, begins Monday. Attorney Karen Conti tells “NewsNation Live” that bodycam footage suggests police did not attempt to de-escalate the situation and that the jury must determine whether Massey posed an imminent threat of serious bodily harm. “Was it imminent? Was she fleeing an arrest? No, she wasn’t,” Conti says. “Was she a danger to them, and were they entitled to use deadly force?”
