A California woman known as 'The Butt Lady' has been sentenced to at least 15 years in prison for the murder of an actress during a botched buttock silicone injection. Libby Adame, 55, was convicted of second-degree murder for administering a lethal dose of silicone oil to Cindyana Santangelo, 58, in March 2025, causing a fatal embolism.
Santangelo, dubbed the 'Latin Marilyn Monroe' by Perry Farrell of Jane's Addiction, had roles in TV shows such as ER, Married…with Children, and CSI Miami, as well as the film Hollywood Homicide. Her son, Dante Santangelo, told the court he was on holiday in Thailand when the incident occurred, saying, 'I did not expect this to happen in my wildest dreams.'
Adame's lawyer, J. Michael Flanagan, argued that his client was merely consulting and that someone else administered the fatal injection. However, the court found her guilty. Frank Santangelo, the victim's husband, condemned Adame, stating, 'I will never have my best friend, my boys won’t have their mom at their weddings. It’s insane that someone would make that choice.'
This is not Adame's first conviction for a lethal buttock injection. In 2024, she was sentenced to four years and four months for involuntary manslaughter in the 2019 death of Karissa Rajpaul, 26, but was released after a year due to time served. Her daughter, Alicia Galaz, was also convicted in that case. Prosecutors noted that Adame had fled a salon in 2018 moments before paramedics arrived to treat another woman who died from a silicone injection, though no charges were filed.
