(CBS/KYW/AP) Investigators in the death of Claudia Aderotimi scoured the home of Padge Victoria Windslowe, a 41-year-old Philadelphia woman accused of injecting an illegal substance into the British woman's buttocks.
Authorities are still searching for Windslowe, a transgender hip-hop singer who also goes by "Black Madame" and who could be charged with murder.
According to court documents obtained by CBS affiliate KYW, police executed a search warrant Thursday and seized dozens of items from Windslowe's home, including a box of syringes, packets of silica gel, and a sterile water bottle for injections.
Aderotimi, 20, a dancer and aspiring hip-hop star, traveled with friends from London to Philadelphia in order to undergo the illegal cosmetic procedure.
According to The New York Daily News, Aderotimi and another woman went to a hotel near the Philadelphia International Airport and paid more than $1,500 to receive injections to make their rear ends curvier.
The other woman survived, but Aderotimi complained of chest pains and trouble breathing and was rushed to the hospital where she died a day after the Feb. 7 procedure.
"She started coughing and having shortness of breath," Lt. John Walker, police spokesman told The New York Daily News. "What we believe happened is that the injector nicked a vein and put the substance into the bloodstream. It goes through your vascular system and lands in the lung and since it's a gel, it will pile up like a rock."
"If that's truly what happened, it's a murder charge," he added.
Police say they will ultimately determine what, if any, crimes were committed once they obtain the results of an autopsy conducted by the Delaware County medical examiner's office and learn Aderotimi's exact cause of death.
Liquid silicone is sought on the black market by women seeking to enhance their figures, even though it is not approved for cosmetic injections. It was not known what substance was used on the women at the hotel. Besides liquid silicone, injections of substances including paraffin, petroleum jelly and hydrogel have been illegally used to enlarge women's breasts, hips and buttocks.
