SANFORD, Fla. -- Police want to see if a prostitute, found dead in Sanford, is connected with a Daytona Beach serial killer.

Investigators will only say the death of 39-year-old Lisa Marie French is suspicious. She was found murdered next to railroad tracks earlier this week.

Detectives have contacted Daytona Beach police about their on-going serial killer investigation, but Daytona Beach police have not commented to Channel 9 about any connections.
