MIAMI (AP) - A woman who wanted to work at a nightclub started searching for someone who could perform plastic surgery at a cheap price to give her a curvier body. Police say what she found was a woman posing as a doctor who filled her buttocks with cement, mineral oil and flat-tire sealant.

The suspect - who police say was born a man and identifies as a woman - apparently performed the surgery on herself, and investigators say she may have victimized others. Oneal Ron Morris, 30, was arrested Friday after a year on the lam and has been charged with practicing medicine without a license with serious bodily injury.

Police photos show Morris as a small-framed woman with bee-stung pouty lips, arched eyebrows, oversized hoop earrings - and a large backside. She was released from jail on bond. A phone listing for Morris could not be found, and it's unclear if she has an attorney.

Miami Gardens Police Sgt. Bill Bamford said Sunday that Morris bounced from house to house for a year, driving a black Mercedes and staying out of investigators' sight "like a ghost." An officer drove by one of those possible houses nearly every day on his way to work and saw the car outside on Friday, and he arrested Morris soon after.

The victim, who is not being named due to medical privacy laws, paid $700 for a series of injections in May 2010. She was referred to Morris by a friend.

Morris injected some type of tube in several sites around her bottom, pumping it full of a toxic concoction. Morris reassured the woman when the pain became too intense, police said.

Bamford said Morris told the woman, "'Oh don't worry, you'll be fine. We just keep injecting you with the stuff and it all works itself out.'"

Bamford said the victim was reluctant to come forward. She quickly went to two South Florida hospitals due to severe abdominal pain and infected sores on her buttocks accompanied by flu-like symptoms. But she left each time, too embarrassed to tell doctors what she'd done.

Her mother eventually took her to a hospital on Florida's west coast, where alarmed doctors pressed her for information. They alerted the Department of Health.

"The doctors knew no licensed physician in his right mind would ever do this," Bamford said.

The victim is still recovering from the surgery and says it's too painful to work. She also has racked up numerous medical bills.

Authorities believe there are other victims who may be too embarrassed to come forward.

"(Morris) was readily introduced to our victim as someone who could help improve her shape, so we believe (she's) done this to other people," Bamford said.
