KAUFMAN, Texas — The wife of a former judge was charged Wednesday with capital murder in connection with the slayings of a North Texas district attorney, his wife and an assistant district attorney, a law enforcement official said.

The overnight arrest of Kim Lene Williams is the latest twist in an investigation that had narrowed on her husband.

Jail records did not yet list a charge, but a law enforcement official with knowledge of the investigation told The Associated Press that Williams was arrested and charged with capital murder. The official said Williams was being held on a $10 million bond at Kaufman County Jail.

The official spoke on condition of anonymity because of the sensitivity of the ongoing investigation into the deaths of Kaufman County Assistant District Attorney Mark Hasse in January and District Attorney Mike McLelland and his wife last month.

The official did not describe the evidence against Williams.

McLelland and Hasse prosecuted Williams’ husband, Eric Lyle Williams, last year in the theft of three computers. A jury found Williams guilty and he was stripped of his law license and lost his elected position as justice of the peace.

I’ve looked at the pics of both of them, and neither one looks like a member of a Mexican drug cartel or Aryan Brotherhood (well, maybe the wife does, now that I think about it).
