A woman in a Florida Taco Bell was reportedly seriously injured when a suspect doused her with gasoline and set her on fire Wednesday night.

The disturbing attack occurred at about 6:15 p.m. at one of the fast food chain’s Tallahassee locations, according to the Tallahassee Democrat.

The suspect, identified by police as 32-year-old Mia Williams, fled and is still being sought.

“At this time, [investigators] are on scene, trying to basically solve this puzzle, to figure out why this heinous crime was committed,” Tallahassee Police Department spokesman Damon Miller told the paper.

Miller said it’s unclear if Williams knew the woman or what may have provoked the attack.

The victim was airlifted to a nearby hospital with serious burns.
