On the morning of May 13, 2011, a small house fire in Ammon, Idaho, revealed a far worse scene. Emergency responders found 19-year-old Malinda Kern, her sister Michelle Kern, 22, and Michelle’s two young sons, ages 3 and 10 months, dead of gunshot wounds inside the family home. Their deaths were accompanied by a fire that had been set in the house.

Authorities identified 26-year-old Gaylin Leirmoe, the father of Michelle’s children, as the person who shot the four victims and then turned the gun on himself. Leirmoe was located with a gunshot wound and later died at a local hospital. At the time of the killings the sisters’ parents were out of town and Michelle and her children had been living in the family home; Leirmoe had recently separated from Michelle and had just arrived at the house.

Was anyone in the Ammon area that night aware of visitors or disturbances at that cul-de-sac who could add details about what happened?
