The man married to the East Texas mom who stoned her three kids wants a divorce. Keith Laney filed for divorce at the Smith County courthouse yesterday. He cites "discord and conflict of personalities as the reason for the divorce. Last month, Deanna Laney was found not guilty by reason of insanity in the deaths of her two sons last May. She severely beat 8 year old Joshua and 6 year old Luke with rocks. The youngest son Aaron suffered severe brain damage. The divorce filing comes weeks after the state notified Keith he would have to pay for his wife's psychiatric care. By law, Mrs. Laney could remain committed for the rest of her life.
