Drew Peterson's attorneys rested their case after a dramatic day of testimony that included Peterson's 19-year-old son.
There was also the risky decision to put divorce attorney, Harry Smith, on the stand who said Stacy Peterson told him Drew Peterson killed his third wife Kathleen Savio.
The defense wanted to attack the credibility of Stacy Peterson and paint her as a greedy liar, so they called divorce attorney Harry Smith to testify about a conversation he had with Stacy shortly before she disappeared.
This allowed jurors to hear that Drew Peterson killed his third wife.
The testimony had jurors scribbling in their notebooks. Smith said that Stacy Peterson called him in late October 2007 saying she wanted to leave Drew and take the kids with her out of state.
She also wanted to know if information she had on Drew, regarding the death of his former wife Kathleen Savio, could help her get more money.
Harry Smith testified: "She (Stacy) wanted to know if, in my opinion... the fact that he killed Kathy could be used against him in a divorce proceeding."
Defense attorneys, who argued in the hallway outside court about whether it was a good idea to call Smith, later appeared unified about the decision.
"Here's what you found out today, you found out that Stacy was going to say anything to gain an advantage in the divorce she was gonna file, we put it in there because it's not credible," said Steve Greenburg.
The spokesperson for Stacy's family called Smith's testimony a God-send.
"I think right then and there sealed the deal for the state, the jury right then heard loud and clear that Drew killed Kathleen that night."
Prosecutors tried to mute how pleased they were.
The defense case ended with testimony from Peterson's 19-year-old son, Tom, who said when his mother Kathleen Savio died, there was nothing out of the ordinary about his father's demeanor.
"I believe that my dad is innocent" he told jurors.
Tom Peterson said the day his father broke the news about his mother's death, he appeared "shaken" adding "I've never seen anyone so sad."
Before the defense rested, the judge asked Drew Peterson directly if he wanted to testify.
Peterson answered, "I will not testify."
Thursday, prosecutors will put rebuttal witnesses on the stand which could include famed forensic pathologist Dr. Michael Baden.
The big looming question is when will jurors hear closing arguments? The judge will probably make that decision on Thursday also.
