Unconventional relationship holds answers to Florida woman's violent murder

In April 2018, in the sleepy Florida Gulf Coast town of Eastpoint, it appeared a killer had struck.

"I received a call that a body was located .. off of Highway 98," Lt. Ronnie Jones, from the Franklin County Sheriff's Office, told "48 Hours" correspondent Peter Van Sant.

Badly beaten and with no identification, the woman became a Jane Doe. Her killer's identity was also a mystery.
