Police say she ran a lucrative cash business doing the black-market injections, charging $1,800 or more for each procedure. Windslowe has been linked to the death of Claudia Seye Aderotimi, 20, who died in February 2011 shortly after Windslowe injected her.
Prosecutor Bridget Kirn wanted bail to remain at $10 million, citing Windslowe's multiple names, identity documents, and addresses as evidence that she was a flight risk.
"She has operated, and continued to operate, an illegal business," Kirn said after the hearing. "What she's doing is preying upon people who are vulnerable, people that are going to her for these services, and perhaps not even realizing they are putting their own lives at risk."
Windslowe's attorney, Chris Mannix, said Windslowe's multiple names could be traced to stage names she used as an aspiring singer, as well as to her former identity as a man. Windslowe has undergone a sex-change operation.
He also denied that she was at risk of skipping town, saying her family in Philadelphia includes a mother, stepfather, three sisters, and nieces.
"She has much support from her family, and she has deep roots in Philadelphia," he said, "and she's not going."
Mannix said he did not know whether Windslowe could make bail.
"It remains to be seen," he said.
Windslowe, who has no medical license or training, is charged with aggravated assault for allegedly holding a "pumping party" Feb. 19 in which she injected a North Philadelphia woman, 23, with silicone or some other substance that caused her to fall ill. Police said that the substance made its way into her bloodstream and lungs and that she was hospitalized, coughing up blood. The woman has been released, but is still on oxygen, and her health problems continue, police said.
Philadelphia Lt. John Walker described Windslowe as "extremely dangerous" and asked any other victims of Windslowe's to contact police.
"She has no concern for these young ladies," he said.
Authorities believe Windslowe has given injections to at least 14 other women since November and said she likely performed the procedure on other women at the "parties" she hosted. The Inquirer has spoken to a New York woman who said she fell into a coma for three months and almost died after receiving injections from Windslowe at a hotel in Mount Laurel, N.J.
Windslowe's preliminary hearing is set for May 16.
