Police have launched a homicide investigation after 19-year-old Jessica Chambers was horrifically burned alive in Panola County, Mississippi.

Chambers was doused in flammable liquid and set on fire. She was found alive, but later died from burns covering 98-percent of her body.

On "The Real Story" today, Trace Gallagher reported that firefighters found Chambers walking down the road, still on fire.

According to Chambers' father, she told the firefighters who she was because she was unrecognizable, and she tried to tell them who did this to her, Gallagher reported.

Gallagher said that the sheriff will not confirm if they have the name of the suspect, but authorities are looking for a person of interest.

Gallagher said investigators believe the killer or killers were inside Chambers' car, bashed her in the head, poured lighter fluid down her throat and then lit her on fire.

Gallagher reported that there is surveillance footage of Chambers at a gas station that shows her walk toward the station and appear to stop and walk toward someone who is off-camera. It is unclear if this plays any role in the crime, he added.

Gallagher said that police are examining Chambers' cell phone records to establish a timeline of what she did all day long and interviewing everyone she had contact with in the hours before her death.

According to Chambers' family, she did not have a boyfriend, but had been involved in an abusive relationship with a man who no longer lives in Mississippi, Gallagher reported.

Anyone with information on the murder is urged to contact the Panola County Sheriff's Office at 662-563-6230.
