On May 17, 2024, “ABC 20/20” will present a compelling episode detailing the tragic murder of Fabio Sementilli, a renowned beauty executive. This episode explores a chilling tale of betrayal, conspiracy, and the relentless pursuit of justice.

The Life and Career of Fabio Sementilli

Fabio Sementilli, born and raised in Toronto, Canada, discovered his passion for hairstyling early and received his certification in 1987. His career was marked by dedication and a strong work ethic, traits inherited from his immigrant family. Despite not having a direct pedigree in hairdressing, Fabio’s talent and commitment set him apart in the competitive beauty industry.

Sementilli’s most notable role was as Vice President of Education for Wella, where he developed programs supporting hairstylists worldwide. His hands-on approach and ability to connect with people earned him the affectionate nickname “Big Daddy” among peers. Fabio’s impact extended beyond professional achievements; he was a mentor to many and a vibrant personality at industry events.

The Tragic Event and Its Immediate Aftermath

On January 23, 2017, Fabio Sementilli was found murdered at his Woodland Hills home by his 16-year-old daughter, Isabella. Initially, the crime appeared to be a robbery gone wrong, but further investigation revealed a more sinister motive involving his wife, Monica Sementilli, and her alleged lover, Robert Baker.

This revelation shocked the community and turned the investigation into a complex case of conspiracy and betrayal. The evidence suggested that the murder was premeditated, driven by Monica and Baker’s desire to benefit financially from Fabio’s life insurance policy worth approximately $1.6 million.

The Investigation and Arrests

In June 2017, Monica Sementilli and Robert Baker were arrested and charged with murder. Additional conspiracy charges revealed premeditation. The evidence included surveillance footage, DNA evidence, and communications between Monica and Baker, indicating a well-planned crime.

In July 2023, Baker pleaded no contest to first-degree murder and conspiracy to commit murder, receiving a life sentence without parole. This plea provided some justice for Fabio’s family, though the emotional impact remains. Monica’s trial, initially set for earlier, is now likely to occur later in 2024, keeping the case in the public eye.


The murder of Fabio Sementilli is a story of betrayal, conspiracy, and the pursuit of justice. As “ABC 20/20” delves into this tragic case, the complexities of the relationships and the enduring quest for truth are revealed. Tune in on May 17, 2024, for an in-depth look at this captivating case that has captured public attention.
