Authorities asked for help Monday to find an ex-con suspected of killing her wife, a veteran state firefighter, at the victim’s Ramona home — more than 20 years after pleading guilty in the slaying of her estranged husband.

Deputies found Rebecca Marodi with multiple stab wounds, and despite life-saving measures, officials said she was pronounced dead on the scene.

Authorities asked for public help in their quest to find Yolanda Marodi, suspected of fatally stabbing wife Rebecca Marodi in her Ramona home.

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.

Yolanda Marodi is the suspect in the killing of Cal Fire captain Rebecca Marodi, detectives in San Diego County said.

A woman accused of stabbing her wife, a Southern California fire captain, to death was previously convicted in her husband’s eerily similar murder more than two decades ago.

Officials believe she may have fled to Mexico driving a 2013 Chevrolet Equinox with California license plate "8BQJ420."

Yolanda Marodi is accused of murdering her wife, 49-year-old California Fire Capt. Rebecca Marodi, almost 25 years after she was charged with stabbing her husband to death
