A woman who performed illegal buttocks enhancement surgeries in Philadelphia was found guilty Monday of third-degree murder in the death of a 20-year-old British woman who was given liquid silicone injections by the defendant, Padge-Victoria Windslowe, in 2011. Windslowe, 45, a transgender woman and self-described hip-hop performer known as the “Black Madam,” had no medical training and had performed thousands of underground butt implant surgeries since 1995, Philly.com reported. Windslowe called herself “the Michelangelo of buttocks injections.”

A Philadelphia jury convicted Windslowe on three additional counts, including aggravated assault for the hospitalization of a 23-year-old stripper named Sherkeei King, as well as two counts of possession of hypodermic needles considered instruments of a crime, according to CBS Philly. King sustained serious injuries after Windslowe injected her with silicone in 2012.

"This case is about justice for these young ladies," Assistant District Attorney Bridget Kirn told the jury during closing remarks, according to Philly.com. Prosecutors argued Windslowe misled her clients into believing she was a licensed medical practitioner and told her customers she was using medical grade silicone when she actually used industrial grade silicone. Windslowe reportedly used Krazy Glue and cotton balls to seal up the injection sites. "It's about taking responsibility and for this defendant to finally take criminal responsibility for what she did,” Kirn said.

Windslowe was arrested in Philadelphia in February 2012 while preparing for a “pumping party” where she planned to inject clients, some of whom had paid thousands of dollars for her work, with silicone, the Associated Press reported. Her trial began last month.

In 2011, Claudia Aderotimi, 20, traveled to Philadelphia from London to have Windslowe perform a butt enhancement surgery on her in an airport hotel room. She later died after the silicone traveled to her lungs, brain and liver, poisoning her.

During the trial, medical experts testified medical professionals no longer used the type of silicone Windslowe injected in her procedures because of its tendency to travel to other parts of the body. Windslowe’s sentencing was scheduled for June.

In the past decade, medical experts and law enforcement have seen a rise in underground butt enhancement surgeries in the U.S., often with people posing as doctors to perform illegal injections. Customers were often offered silicone injections at a fraction of the price they would pay a plastic surgeon. Such illegal surgeries often take place in hotel rooms, basements or even garages.
