Former and *current* attorneys for Drew Peterson are fighting over who's to blame for the Chicago cop's murder conviction last year.
Peterson's one time lead attorney Joel Brodsky has filed a 31 page lawsuit accusing current attorney, Steve Greenberg of defaming him.
It also names the Chicago Tribune and AOL's Patch News web site.
The two attorneys started pointing fingers after Peterson was found guilty back in September of drowning his 3rd wife, Kathleen Savio in her bathtub.
