A Cal Fire captain was fatally stabbed at her home in Ramona Monday in what San Diego County Sheriff's Department officials are investigating as a suspected homicide.

Detectives with the San Diego Sheriff's Department "are treating this case as a potential domestic violence incident," officials said

Captain Rebecca "Becky" Marodi served over 30 years with CAL FIRE. Homicide Unit detectives are working to determine the circumstances that led to the woman’s death and the possible motive.

An off-duty Cal Fire captain was found fatally stabbed inside her Ramona home Monday evening, and sheriff’s detectives are investigating the homicide as a possible domestic violence case, officials said.
