A Southern California woman has been sentenced to 15 years to life in prison after being found guilty of causing the death of a Hollywood actress through a failed silicone injection procedure. The sentencing took place on Wednesday.

Libby Adame, aged 55, was convicted earlier this month in Riverside County on charges of second-degree murder and practicing medicine without a license. The charges were related to the death of Cindyana Santangelo in March 2025, following a silicone injection administered at Santangelo’s Malibu residence.

Cindyana Santangelo, 58, was known for her roles in television series such as “CSI: Miami,” “ER,” and “Married with Children.” She also appeared in the music video for Young MC’s 1989 classic, “Bust a Move.”

During the trial, Frank Santangelo, Cindyana’s husband, recounted how Adame fled their home when his wife began experiencing severe convulsions after the procedure.

Authorities revealed that Adame had a history of performing unauthorized silicone buttock injections, raising concerns about her previous activities.

In 2024, she was convicted of involuntary 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 with the procedure, received three years and eight months.

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 Adame was aware of the risks associated with silicone injections well before these deaths.

According to the Los Angeles Times, security camera footage from 2018 captured her fleeing a South Gate salon as paramedics treated another woman who later died – an incident predating both Rajpaul’s and Santangelo’s fatalities.
