The San Diego County Sheriff’s Department on Thursday identified the person they believe to be responsible for stabbing a Cal Fire captain to death in her Ramona home earlier this week.

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

A manhunt is on for Yolanda Marodi, the wife of a California fire captain who was stabbed to death earlier this week in her San Diego-area 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.

San Diego Sheriff's Office identifies Yolanda Olejniczak as a suspect in the murder of Fire Captain Rebecca Marodi. They've been married for two years.

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 asked the public Friday for help in finding an ex-con suspected of killing her wife, a veteran state firefighter, in Ramona.
