The murder trial of former suburban police officer Drew Peterson was always going to hinge on his dead ex-wife's testimony "from the grave" and other hearsay evidence.
But no one anticipated just how troublesome the trial has become for prosecutors. The judge has considered at least three defense motions for a mistrial after prosecutors talked about or asked about things that they shouldn't have.
The looming question as the trial goes into its fourth week is whether or not the problems have hurt prosecutors' credibility with the jury. It's a case where they absolutely need jurors to believe their version of events because no physical evidence links Peterson to the 2004 death of Kathleen Savio.
