On Saturday night, Marc Williams, 29, of Lakeland, poured gasoline in her car and lit it on fire in the Rock-n-Rodeo parking lot, said Lowndes County Sheriff Chris Prine.
Investigators say Williams was arrested shortly afterward while trying to leave the scene.
Williams, who's charged with one count of arson in the first degree, was booked into the Lowndes County jail.
He then bonded out on $150,000.
No injuries were reported.
