NEW ORLEANS — A Mississippi sheriff’s investigator hopes surveillance video from Bourbon Street in New Orleans will provide clues about the death of a strip club dancer whose dismembered body washed ashore on the Gulf Coast.

Hancock County Chief Investigator Glen Grannon said Sunday that 22-year-old Jaren Lockhart reported for work Tuesday night and left early Wednesday. Her torso was found late Thursday in Bay St. Louis. Other body parts, including her head and parts of her legs, were found later.

It remained unclear where Lockhart was killed and dismembered and where the body parts were put in the water. Grannon said experts on tides would be consulted Monday to help determine where the body parts were likely dumped.

Lockhart had been living at a New Orleans motel. New Orleans police said she had been reported missing last week by her boyfriend, who said he became concerned because he was unable to contact her after she left for work Tuesday night.

“We know she made it to work and left in the early morning hours,” Grannon said. He said there is some surveillance video showing her leaving the club. He would not go into detail about who she left with. Investigators have been working with New Orleans police and interviewing people who knew or might have seen Lockhart. He said they also planned to check video from other nearby businesses.

Lockhart had been a resident of the Capri Motel, a $50-a-day motel frequented by Gulf oil workers between offshore stints and by French Quarter bar employees.
