Drew Peterson's defense team rested its case after Peterson told the judge he would not testify in the trial.
Judge Edward Burmila asked Peterson Wednesday whether he had reached a position as to whether he would testify.
“I will not testify,” Peterson told the judge.
The prosecution’s rebuttal case will begin Thursday morning. Earlier on Wednesday, Drew Peterson’s son Thomas testified that he did not believe his father killed his mother, Kathleen Savio.
Defense attorney Joel Brodsky asked Thomas Peterson, “At any time after your mom passed away, did you ever tell anybody that you suspected that your dad had killed your mom?”
“I have not once suspected that,” he replied.
Thomas Peterson said he was in court voluntarily because he believed his father was innocent.
Savio's death was initially ruled an accident, but investigators reopened the case in 2007 when Peterson’s fourth wife, Stacy Peterson, went missing. Investigators exhumed and re-examined Savio’s body and ruled that her death was a homicide. Stacy Peterson’s whereabouts are still unknown, and Peterson is not facing any charges related to her disappearance.
Peterson has pleaded not guilty to murder charges in Savio's death and has been on trial since late July. There are no cameras allowed in the courtroom, but In Session on truTV is covering the trial from the Joliet, Illinois, courthouse.
