September 18, 2012 (JOLIET, Ill.) --
Closing arguments in Christopher Vaughn's murder trial are scheduled to begin on Thursday. In court Tuesday, Vaughn announced that he will not testify. The defense has rested its case.
Vaughn is accused of killing his wife and three children in 2007. He claims his wife shot him and their children before committing suicide.
Also in court Tuesday, a blood stain expert testified that his analysis of what happened did not match up with Vaughn's story.
