A Southern California woman convicted of killing a Hollywood actress with a botched silicone injection into her buttocks was sentenced to 15 years to life in prison on Wednesday.
Libby Adam, 55, was convicted earlier this month in Riverside County of second-degree murder and practicing medicine without a death certificate in March 2025. Cyndiana Santangelowho received the injection at her home in Malibu.
Santangelo, 58, has appeared in television shows including “CSI: Miami,” “ER,” “Married with Children” and the music video for Young MC’s 1989 song “Bust a Move.”
During the trial, Santangelo’s husband, Frank Santangelo, testified that Adam fled their home when his wife began convulsing after the injection.
Adame had a prior history of performing unauthorized silicone buttock injections.
In 2024, she was convicted of manslaughter for the 2019 death of 26-year-old Karissa Rajpaul in Sherman Oaks. She was sentenced to four years and four months in prison, while her daughter Alicia Galaz, who assisted in the action, was sentenced to three years and eight months.
They both received credit for time already served and electronic monitoring, allowing Adame to resume cosmetic procedures within a year.
Prosecutors also presented evidence suggesting that Adam knew of the risks associated with silicone injections long before these deaths.
According to Los Angeles Timeswas captured on a security camera from 2018 as she fled a Southgate salon while paramedics treated another woman who later died — an incident that preceded the deaths of both Rajpaul and Santangelo.
