PANOLA COUNTY, Miss. — Jessica Chambers’ mother, Lisa Chambers, told WREG she has “full faith” that there will be justice for her daughter.

Chambers is aware of several rumors circulating in the area about the circumstances of her daughter’s death and said she finds them counterproductive.

“Just shut up when you don’t know what you’re talking about. I mean that’s really ridiculous,” Chambers said.

Chambers said she appreciates the presence of the Panola County Sheriff’s Office, the FBI, the ATF, and the U.S. Marshal’s Office.

She is also grateful to the private sources that are contributing to CrimeStoppers’ reward.

A $1,000 reward was originally offered, then $10,000 was added by the U.S. Marshal’s Office.

Wednesday, the Mississippi Fire Marshall added an additional $5,000 to the reward.

Monday, the FBI joined the investigation.

Chambers was found burning and died in Panola County December 6th.

Investigators say Chambers was burned over 98 percent of her body. Autopsy results have been finalized but not released to the public.

The gas station worker who spoke to Jessica the night she died told WREG he is receiving death threats.

The employee, Ali Alsanai, went to the Panola County Sheriff’s office Monday to try to get an order of protection.

“They came to the store, they asked for the surveillance video. I showed them the surveillance video. The next day, they came and asked for the camera, so I gave them the camera system. What else can I do?” he said.

There has been online speculation Alsanai was not telling the truth and might be involved, but there is no proof of that so far.
