Mike McLelland Murder Update: According to affadavit, Kim Williams, wife of former judge Eric Williams, confesses in Texas DA slayings

(CBS/AP) KAUFMAN, Texas - Authorities say the wife of a former judge has confessed to being involved in the shooting deaths of a North Texas district attorney, his wife and an assistant prosecutor.

Kim Lene Williams was arrested early Wednesday. Kaufman County sheriff's spokesman Lt. Justin Lewis says Williams is being charged in all three deaths. Lewis says she is being held on $10 million bond.

According to an arrest warrant affidavit, Williams told investigators Tuesday that she was involved in the shootings of Kaufman County District Attorney Mike McLelland, his wife, Cynthia, and one of his prosecutors, Mark Hasse.

Williams gave details of both slayings that have not been released to the public, according to the affidavit.

The investigation has also focused on her husband, Eric Williams, whom McLelland and Hasse successfully prosecuted for theft.  CBS Dallas reports that Hasse and McLelland secured a conviction against Williams in 2012 after surveillance cameras captured him taking computer equipment from a county building.

The McLellands were found dead March 30, two months after Hasse was slain.
