An exotic dancer's death at an airport hotel has led Philadelphia police to investigate the strange underworld of "pumping parties" and illegal cosmetic surgery.

An aspiring rapper known as "the Black Madam" is accused of killing the 20-year-old dancer from London during a procedure that involved silicone buttocks injections and Krazy Glue.

Padge Victoria Windslowe's third-degree murder trial is expected to start Thursday in Philadelphia Common Pleas Court.

Police say that Windslowe fled the hotel room after Claudia Aderotimi started having trouble breathing during "a touch-up" to celebrate her birthday in 2011.

A coroner has testified that the industrial-grade silicone spread to her lungs and brain and caused a pulmonary embolism.

The defense is expected to challenge the medical evidence.

Windslowe also is charged with practicing medicine without a license.
