Laura suffered through an abusive relationship for years. Grant cheated on her openly and beat her into submission. When she finally left, there were two babies involved. A custody battle became heated. Accusations were thrown from both sides. Laura initially only had her two sons on the weekends. But after a psychological review of all parties, there was hope on the horizon. But that was dashed when Grant realized he was fighting a losing battle. Instead of split or lose custody he chose to end the life of their mother. In the end two sons lost both parents.
