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.

Rebecca Marodi was found in her San Diego-area home Monday. A woman has been identified as a suspect in her slaying, but her whereabouts are unknown.
