Former deputy accused of killing Sonya Massey testifies at his trial

Sean Grayson, the former Illinois sheriff's deputy accused of killing Sonya Massey, testified at his trial Monday, telling the jury he thought Massey was going to throw a pot of boiling water at him. Investigators say Grayson shot and killed Massey in her home after she called 911 about a possible prowler. Grayson has pleaded not guilty. Warning, the video in this story is disturbing.
