A former madam has been convicted of third-degree murder in the death of a British dancer who got silicone injections to enhance her buttocks at an airport hotel.

Padge-Victoria Windslowe told a Philadelphia jury she performed thousands of the procedures despite a lack of formal medical training.

The 45-year-old Windslowe describes herself as a former madam and hip-hop performer known as "the Black Madam."

Police say she fled after a botched injection killed the 20-year-old London dancer in 2011.

Windslowe was also convicted Monday of aggravated assault for injuries to another woman who was hospitalized after silicone from an injection spread to her lungs.

Windslowe says women paid thousands of dollars for her work and called her "the Michelangelo of buttocks injections."
