Late Wednesday afternoon, police were obtaining an arrest warrant for the woman. They have not yet identified her publicly.
Friends and co-workers told Eyewitness News the victim, who they identifed as T.J. Haley, was to undergo skin graft surgery on Wednesday.
Police said a woman used some type of accelerant on the victim, setting him on fire just before 6 a.m. in the 500 block of 21st Street.
"Honestly, I was not surprised. She has been harassing him off and on since they broke up about five or six years ago," said friend and co-worker Megan Walker.
She said Haley has worked for years at the Saltwater Grill, a restaurant just across the street from the scene of the attack.
"He and I just had a conversation on Monday. He's like 'Megan, I think I gotta change my number,'" she said.
Walker added that Haley told her he was growing more and more concerned about the behavior of his ex.
"God forbid anybody talks to him. When she sees them she's not happy about that," said Walker.
Police said the attacker will likely face a charge of aggravated assault causing serious bodily injury. If convicted, the suspect could be sentenced up to 99 years in prison.
