Jessica Lane Chambers, a Mississippi teen who was burned alive Saturday, was captured on surveillance video hours before her tragic death.

"The [Panola County Sheriff's Office] has the video now and they've been going over it," Jessica's father, Ben Chambers, told The Huffington Post.

WMC-TV, an NBC affiliate in Memphis, Tennessee, reportedly discovered the video at a gas station on Highway 51 in Courtland, a small Mississippi town located about an hour south of Memphis. The station reportedly notified police of the video, and authorities are investigating.

In the video, Jessica Chambers, 19, can be seen waving to someone before walking over to them, out of the camera's view. She eventually returns to her car and drives away.

A man carrying a gas can is also visible in the video, but authorities have said the man was getting gas for a generator and is not associated with the investigation.

It remains unclear why police had not uncovered the video during the course of their investigation. Calls for comment to the Panola County Sheriff's Office, where Ben Chambers is a maintenance worker, were directed to Panola County District Attorney John Champion. Calls to Champion's office by The Huffington Post were not returned Wednesday.

Jessica Chambers was found Saturday badly burned on a road near Highway 51. A passerby discovered the girl not far from her vehicle, which had been set ablaze.

According to Chambers' father, "whoever did it squirted lighter fluid or something like that down her throat and set her on fire."

Chambers died just hours later at Regional Medical Center in Memphis. An initial autopsy report revealed the teen died from severe burns that covered 98 percent of her body, NBC affiliate WFLA reported.

Ben Chambers said he believes that whoever called his daughter out of the camera's view in the surveillance video may have information in the case.

"Some people are saying she stopped by a party after that," said Chambers. "We think whoever called her over to them was asking her to go to that party, because where she was found and where the party was aren't very far apart."

Chambers said he does not believe his daughter had planned to attend a party that night, because she was "not dressed up" and she had told her mother she was going to a car wash.

Chambers said he has been told by police that when first responders arrived at the scene of the fire, his daughter whispered to them the first name of the person responsible.

"I believe in all my heart she knows who it was," he said.

Authorities have yet to confirm that information. No suspects or persons of interest have been named, and it's unknown what evidence, if any, was recovered from the teen’s burned-out vehicle.

"They won't tell me very much right now," said Chambers. "They promise me things are looking good -- they got folks going in any different directions -- so we hope to know something before the day is over."

Anyone with information in the case is asked to contact the Panola County Sheriff's Office at 662-563-6230 or the Mississippi Bureau of Investigation at 662-563-6400. The teen's friends have also created a Facebook page, Justice for Jessica, to share information in the case.
