The remains were discovered during a search of a burnt mobile home. The Riverside County Coroner’s Office is attempting to identify the body.

The first body discovered has been identified as Lois Arvikson, 89, of Calimesa.

CalFire peace officers said the cause of the fire was a trash truck that dumped a load of burning trash into vegetation. The site where the burning trash was dumped remained cordoned off with crime scene tape.

Arson and homicide investigators were on the scene and working to determine whether anyone would be held responsible for the death caused by the fire, Riverside County Sheriff Chad Bianco said.
