BAY ST. LOUIS, Mississippi -- The torso found with a stab wound in its chest on a Bay St. Louis beach is that of Bourbon Street stripper Jaren Lockhart, 22, who had been missing since she last worked Wednesday morning, said Hancock County Sheriff's Chief Investigator Glenn Grannan.

More body parts were discovered Saturday, from Pass Christian to Long Beach, he said.

Discovery of the head confirmed investigators' focus that the torso was that of Lockhart, Grannan said.

"We went down to New Orleans last night (Friday) and we were working on putting a few more pieces of the puzzle together to confirm our suspicions of it being the girl from New Orleans," he said.

Grannan said New Orleans police have joined the investigation.

"We were able to come up with a few more things that gave us pretty good confidence that we had the right one," he said. "So, we turned our focus on trying to find out who is responsible."

Grannan said there are a number people investigators have yet to talk with, but they did interview about 25 people.

"We know she was at work that night and she left early in the morning," he said. "That's all we know. We are not sure who she left with."

Grannan said Lockhart was liked and "a lot of favorable things were said about her."

But, Grannan said, "We don't know where it took place. We don't have a crime scene."

The victim was dead before she was dismembered, he said.

Along with the head, a lower and upper leg portion, Grannan said clothing was found on the beach Saturday, and it is linked to Lockhart.

The investigation also is waiting for DNA samples this week.

The torso, found at Bay Oaks Drive, had three piercings for jewelry, and there was evidence of other wounds beside the stab wound in the chest, he said.

On Friday, Grannan said the body appeared to have been dead and in the water for about two days, he said.

"Generally, things that show up on our beach tend to come from the west," he said.
