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.

Marodi was the primary caregiver of her 77-year-old mother, who lived with her in Ramona. Her sudden passing left her family facing immense grief and uncertainty, the Cal Fire San Diego Benevolent Fund stated.
