NEW ORLEANS -- It's been more than four months since Jaren Lockhart's dismembered body washed up along the beaches of Hancock County, Mississippi, and detectives there are still trying to find out who killed her, and why.
Investigator Steve Saucier, with the Hancock County Sheriff's Office, said his team has run into plenty of obstacles along the way.
'There's not a lot of people talking about this. There's not a lot of people that want to come forward, that want to speak to us, and we urge those people to come to us,' he said.
Lockhart was last seen alive leaving Temptations, the nightclub on Bourbon Street where she worked, in the early morning hours of June 6.
Surveillance images showed her with a couple, identified by police as Terry Speaks and Margaret Sanchez. Authorities arrested the two on unrelated charges.
Sanchez was eventually released, while Speaks remains behind bars in North Carolina on charges of failing to register as a sex offender.
While both Speaks and Sanchez remain suspects, authorities are still trying to piece together clues.
'It's definitely been one of the most challenging cases I've ever worked on. It is without a doubt, the most heinous case I've ever worked on,' Saucier said.
Saucier said evidence has been hard to come by, but items have been collected through the course of the investigation.
That evidence, officials said, is still being processed by the FBI in Virginia.
As investigators chase some promising new leads, Saucier said he recently decided to visit Lockhart's mom.
'One of my main goals was to reassure her that this still was an active case, that it wasn't a cold case, that we were actively working on it,' he said. 'We don't want to leave any stone unturned. We don't want to leave any lead unfollowed.'
Saucier believes his team is on the right track, and he says they're more determined than ever to bring justice to Jaren's family.
'Once we get to know who (Jaren) was -- the mother she was, the friend she was, the child she was -- it's very difficult at times, because you want some resolution and I will not stop until it is resolved,' he said.
