Philadelphia's "Black Madam" was sentenced to at least 10 years in prison Thursday over the 2011 death of a British tourist she'd given an illegal silicone butt injection.

Padge Victoria Windslow was sentenced to 10 to 20 years in prison after being convicted of  third-degree homicide charges for the death of Claudia Aderotimi, 20. 

Windslowe, a transgender recording artist, defended herself at trial as the “fairy god mom” of women seeking inexpensive cosmetic surgery with her pumping parties that administered silicon injections to the breasts and buttocks of several women.

During Thursday's two-hour hearing, prosecutors and defense attorneys sparred over whether Windslowe's actions behind bars were evidence of her remorse, or a continuation of her past conduct.

Prosecutors scolded Windslowe, who wore a white knit dress and matching jacket to court, for advertising a new business while in prison. The business sells pants that helped push fat from the hips to the behind, giving women who wear them bigger butts. 

Prosecutors contend that the brochure advertising the pants used "medical" language. 

The district attorney also criticized her for the foundation she'd started from behind bars in the name of the woman she killed, which sells t-shirts for a charity walk in the British woman's name. 

"She is actually distributing brochures for a walk that doesn't exist, for a charity that doesn't exist, in the victim's name," said assistant district attorney Bridget Kirn.

Windslowe said she was trying to help Aderotimi's family. As for the pants, she says she's selling them to help women get the figure they desired without having to go through silicone injections.

The pants are being offered for sale at $200. The t-shirts for the charity walk are $50 online. It's unclear if Windslowe raised money or sold any pants. The judge noted that she had sent her brochure to every judge in Philadelphia's Criminal Justice Center.

During the trial, prosecutors argued the industrial-grade silicone put women's lives in danger. Other women who had received the injections had suffered breathing problems or lived in fear that the silicone could cause health problems down the road.

Judge Rosemarie DeFino-Nastasi noted that she had received hundreds of letters from women at Riverside Correctional Facility, where Windslowe is being housed, urging a lenient sentence. 

Many of those letters argued that the women who were injured by the injections were also at fault because they willingly subjected themselves to the injections.
