A madam who performed illegal "body sculpting" with low-grade silicone injections has been sentenced to 10 to 20 years in prison after a London dancer died in Philadelphia.

Padge-Victoria Windslowe told jurors during her spring murder trial that clients call her "the Michelangelo of buttocks injections."

But prosecutors say she had no medical training and used deadly products on vulnerable women who wanted curves.

A judge describes Windslowe as a narcissist who ignores the law and acts surprised when things go wrong. And she says she hurt at least one other woman even after the 20-year-old died in 2011.

Prosecutors complained Thursday that Windslowe has been trying to raise money in the victim's name while in prison. The judge ordered her to stop.

Windslowe once ran a transgender escort service and performed as "the Black Madam" in Gothic hip-hop videos.
