The wife of a disgraced ex-judge was arrested after admitting Wednesday that she aided her husband in killing a north Texas district attorney, his wife, and an assistant prosecutor. Kim Lene Williams was arrested just four days after her husband, Eric Lyle Williams, who was taken in Saturday. The two murdered prosecutors worked to convict Eric of stealing computer monitors from a county building in 2011. Investigators broke open the case this weekend, when they discovered a storage unit linked to Eric that contained 20 guns and a car that matched the one used in at least one of the killings. District Attorney Mike McLelland and his wife were found dead in their home March 30, just two months after Kaufman County assistant prosecutor Mark Hasse was gunned down.
