Shelly Autumn Mae Moon was 16 when she was killed on February 10, 2021, in a triple homicide at a home on the Bear River Band of the Rohnerville Rancheria Reservation in Loleta, California. A juvenile in the home called 911 reporting a shooting; deputies found two people dead and a third critically injured who later died at a local hospital. Two children, ages 11 and 13, were in the house and unharmed.

The suspect was an 18-year-old guest known to the victims, identified as Mauricio Eduardo Johnson. He had a relationship with Shelly and had been given permission to be in the house by at least one resident. Motive was not immediately clear and detectives continued to investigate. Shelly and another victim, Margarett Lee Moon, were aides at Loleta Elementary School and were remembered for their work with students.

If anyone knew Shelly, her routine, or saw something unusual in Loleta around February 10, 2021, contact investigators with any information.
