Evidence found at the scene proves Sharmeka Moffitt lied about being set on fire and having her car smeared with racist graffiti, police said Tuesday.
The 20-year-old Louisiana woman told police on Sunday night that three hooded men set her ablaze, but she was able to douse the flames herself and call 911.
After analyzing the lighter fluid and cigarette lighter, police found her fingerprints and female DNA, NBC News reported.
“With this evidence, investigators were able to determine that she was alone in the park that night and made up the story,” Capt. Doug Cain of the Louisiana State Police said on NBCnews.com.

Moffitt said she drove to a local park in Winnsboro, Louisiana to exercise when the men wearing "white hoodies" attacked her, The News Star reported.
Police also found racial slurs, including KKK, written on her car with toothpaste.
Moffitt remains in critical condition at LSU hospital in Shreveport.
“Basically we had to follow the facts,” Franklin Parish Sheriff Kevin Cobb told a news conference.
“This was a disturbing case for all involved. All indications show this was a self-inflicted situation.”
