JOLIET, Ill. (MCT) — Testimony in the trial of Christopher Vaughn for the murder of his wife and three children ended today with prosecutors playing the dramatic conclusion to Vaughn’s videotaped police interview, showing Vaughn as he crumpled up a photo of his son 8-year-old son Blake.

After more than 12 hours of questioning, Vaughn had finally had enough. He asked if he was under arrest, and when told he wasn’t, he asked for State Police to unlock the interview room door so he could leave and get some sleep.
