ORANGE COUNTY, Fla. -- An Orange County employee is accused of bringing a prostitute into a county-owned building, beating her up and then trying to pay her to drop the charges.

Kevin Johnson is charged with battery, soliciting a prostitute and tampering with a witness. The county has also launched an internal investigation into his alleged behavior.

Janelle Chapman, who admits she's a prostitute, said she was beaten inside an Orange County utilities building after a county employee, named Kevin Johnson, picked her up along Orange Blossom Trail.

"I do what I do, but I'm still a person," she said.

She said, one night last month, she finally decided to fight back against alleged abuse at the hands of Johnson.

"He goes, 'Where do you want it? Your head or your belly?' I didn't know what he meant by that until he hit me in the side of my face," she explained.

Chapman said Johnson brought her to the building and beat her. The allegedly graphic and sexual beating is described in a police report, but it’s a claim Johnson denies. Detectives do not believe him.

"She clearly stated, 'If I'm doing something illegal, why would I come forward and make an allegation like this?' I have more to lose that just to make up a story.' So we believe that she is factual and she is telling us the truth," said Cpl. Carlos Torres, Orange County Sheriff's Office.

Investigators are not pushing for sexual battery charges against Johnson. He reportedly told detectives he'd paid for sex and that Chapman beat herself. Although he passed a voice stress analysis test, investigators found inconsistencies in his story that led to his arrest. Chapman said she's relieved.

"It's better that than me taking it into my own hands. I'd have probably killed him," she said.

Late Tuesday afternoon, Chapman has resigned from his job. He was an electrician who worked on lift stations.

Chapman claims Johnson offered her $500 to drop the charges. He's already bonded out of jail and declined an on camera interview Tuesday.
