On May 13, 2011, 22-year-old Michelle Shell Kern was found dead in her family home on Amber Lane in Ammon, Idaho, along with her sister Melinda Kern, 19, and Michelle’s two young sons, ages three and nine months. All four victims suffered gunshot wounds. A neighbor reported a fire at the residence in the early morning; investigators later found that a fire had been set in the basement.

Authorities identified 26-year-old Gaylin Leirmoe, Michelle’s ex-boyfriend and the father of her children, as the shooter. Leirmoe, who was living in Iowa, had come to the home while Michelle’s parents were out of town. After the shootings he set the basement fire and inflicted a fatal gunshot wound on himself; deputies found him unconscious and transported him to a hospital where he later died. Investigators reported a history of domestic battery charges against Leirmoe in Idaho that were later dropped, and noted prior violent incidents in Iowa.

The incident was ruled a murder-suicide with Leirmoe the sole suspect. If anyone knew Michelle or her family, or has information about the events leading up to May 13, please come forward.
