Yolanda Marodi, who is suspected in the slaying of her wife, a Cal Fire captain, pleaded guilty in 2004 to voluntary manslaughter in the fatal stabbing of her then-husband.

Marodi, 49, a captain with the California Department of Forestry and Fire Protection (Cal Fire), was found at her Ramona residence with multiple stab wounds on the night of Feb. 17, after deputies responded to a call for an assault with a deadly weapon, according to a statement from the San Diego County Sheriff’s Office.

Authorities have identified the suspect in the fatal stabbing of the California fire captain who helped battle the Eaton wildfires in Los Angeles as her wife, with officials noting this was not her first murder.
