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.

Deputies from the San Diego Sheriff's Office found Rebecca Marodi, 49, in her home with multiple stab wounds on Monday. She died at the scene.
