Drew Peterson Update: Divorce lawyers says Stacy threatened to accuse Drew of the Savio murder

Update from the ABA journal:  Drew Peterson defense attorneys put on testimony from a divorce attorney that 4th wife Stacy Peterson spoke to.  He testified that she considered using the threat of accusing him of murder to gain an advantage in her potential divorce proceeding.  Of course, she disappeared before any divorce proceeding could be commenced.  Does this testimony help Peterson… or suggest more of a motive to have murdered Stacy? (He has not been charged in Stacy’s disappearance… yet.)
