UPDATE: According to a prosecutor, after obtaining warrants and cracking a password, police were able to access Jessica Chambers' phone records.
Authorities are searching her data records and text messages for further leads.
It had been reported that an accelerant had been poured directly into Chambers' mouth and nose, but officials say those details are still unclear; it may have been poured on her car.
PANOLA COUNTY, Miss. - Investigators are looking into a horrific murder after a teenager was burned alive.
Family members of 19-year-old Jessica Chambers says someone poured an accelerant down her throat and nose before setting her and her car on fire.
Authorities say Chambers was still alive when first responders got to the scene.
Some say she tried to whisper the name of her killer to paramedics before she died, but investigators won't go into detail about what she told them.
Once at a nearby hospital, Chambers died from her injuries.
“98 percent of her body was burned. The only thing that wasn’t burned was the bottom of her feet. It’s just destroyed our family, it’s destroyed our family. She was a loving child, 19-years-old. Just finished high school, had her whole life in front of her,” said Ben Chambers, Jessica's father.
Investigators believe her phone will be “the key to everything,” said John Champion, district attorney for Mississippi’s 17th Circuit.
Before she was killed, she stopped at a gas station to fill up her car.
"She seemed normal," said Ali Alsanai, the clerk at the station. "She didn't seem like something was going wrong, you know? She just seemed normal."
So far, investigators have not named suspects in the case.
