Dana Marie Robertson was 42 when she was shot dead in her Casper, Wyoming, home on the evening of March 20, 2020. The killing occurred during a domestic dispute at the couple’s residence on Maple Street. He had briefly kicked her out two weeks earlier before they reconciled.

That night Dana told Edward she thought they should separate but planned to continue helping with his medical needs. She made a makeshift bed in a spare room and was playing on her phone when Edward retrieved a .380-caliber pistol from a dresser drawer, entered the room, turned on the light and fired a single shot, striking her in the head. Edward called 911 after the shooting, told the dispatcher he had done it and was angry because she was cheating on him; he was arrested at the scene without incident. He was charged with first-degree murder and bound over for trial with bond set at $500,000 cash only.

Does anyone have information about Dana’s life in Casper or the Maple Street neighborhood that could shed light on what led up to that night?
