Crime Mother and Daughter Arrested for Murder After Allegedly Performing Illegal Plastic Surgery at Home Karissa Rajpaul, 26, died after undergoing an unauthorized butt-implant procedure performed by Libby Adame and Alicia Galaz, according to police By Katie Campione Katie Campione Digital News Writer, PEOPLE People Editorial Guidelines Published on September 20, 2021 07:25PM EDT A Los Angeles mother-daughter duo has been arrested for allegedly performing an illegal plastic surgery that resulted in a woman's death. Karissa Rajpaul, 26, died after undergoing an unauthorized butt-implant procedure performed by Libby Adame and Alicia Galaz on Oct. 15, 2019, police told KCAL9. Rajpaul's cause of death is listed as homicide due to acute cardiopulmonary dysfunction and intramuscular/intravascular silicone injections. She died at the hospital on the same day the procedure was performed, according to the Los Angeles County Medical Examiner's Office. Investigators believe that, during the procedures, Adame and Galaz — who allegedly presented themselves as specialists — injected Rajpaul with substances used by qualified cosmetic physicians but combined them with dangerous chemicals, ABC7 reports. "They were mixing them with chemicals and other substances that clearly are not appropriate for any medical procedure that would be performed on a human," LAPD Deputy Chief Alan Hamilton told the news station. He added, "These individuals have no medical training. They're not experienced and they're putting people's lives at risk."
