(North Port, FL) -- Crews in Florida will be back out searching Wednesday for a Florida man named a person of interest in his fiancee's death.  

He returned home from a cross country road trip without 22-year-old Gabby Petito. The couple was stopped once for fighting and police body cam video hints at possible domestic violence.  

The case has gripped the nation but experts say the bigger picture is much deeper, with three women killed daily by a current or former partner.
