A transgender woman who claimed to be "the Michelangelo of buttocks injections" has been convicted for the death of a British dancer in a botched 2011 operation.

Padge-Victoria Windslowe was found guilty of third-degree murder for killing 20-year-old dancer and student Claudia Aderotimi. She had injected into Aderotimi's buttocks nearly half a gallon of silicone which eventually moved to her lungs, causing her heart to stop.

Windslowe faces 40 years in prison for the murder charge. She was also charged with assault.

Prosecutors said Windslowe had no medical training to conduct the procedure. They said she only learned to inject silicones from tips she got from doctors who performed her sex change operation.

Windslowe also learned from another doctor, who became her client in an escort service.

"I think it was a hoax, like her whole life has been a hoax," Assistant District Attorney Carlos Vega said on Monday.

The tragic incident began in 2012, when Aderotimi visited Philadelphia, Pennsylvania, to celebrate her birthday with a friend. That friend introduced Aderotimi to Windslowe whom they only knew as "Lilian".

The dancer asked Windslowe whether the silicone injection could interfere with her ability to conceive.  Windslowe reassured her that she is trained to perform the procedure.

Aderotimi complained of chest pains right after the injection, while Windslowe continued to pretend to be a professional nurse and went on to examine her.

Windslowe meet her clients by going to hotel rooms and attending "pumping parties". These are held in undisclosed places for women who want to get that silicone fix.

Windslowe would bring everything she needs in her shiny pink bag. Her tools include a water bottle containing industrial grade liquid silicone, a red plastic cup, needles and syringes, and Krazy glue to close the wound.

The jury decided to convict Windslowe of third-degree murder --- a crime which is not premeditated but involves malice.

Several other similar incidents have been reported in the past, as more people opt for cheap, but unsafe procedures not knowing this could lead to tragic consequences.

The FBI confirms it is investigating more of these cases.
