A woman suspected of killing her wife, a Cal Fire captain, was sentenced in 2004 to 11 years in prison for fatally stabbing her then-husband, sources say.

Rebecca's wife, Yolanda Marodi—also known as Yolanda Olejniczak— was also a veteran firefighter with Cal Fire, having served more than 30 years in the department. Despite her being widely respected by colleagues, Yolanda has been named the primary suspect, according to the San Diego County Sheriff's Office.
