Wife's Lover Convicted in Hair Exec Murder Plot
24 Jan
Summary
- Monica Sementilli orchestrated her husband's murder for financial gain.
- Her lover, Robert Baker, a former porn actor, carried out the stabbing.
- Monica Sementilli received a life sentence without parole in June 2025.

Hair executive Fabio Sementilli was murdered in January 2017 in his Woodland Hills, California home. Prosecutors alleged that his wife, Monica Sementilli, conspired with her lover, Robert Baker, a former adult film actor and convicted sex offender, to kill Fabio. The plan was to make the murder look like a burglary gone wrong so Monica and Baker could be together.
Investigators became suspicious when Monica Sementilli quickly pursued a $1.6 million life insurance payout after Fabio's death. Monica and Baker were arrested in June 2017. In April 2025, a jury found Monica guilty of murder with special circumstances, including financial gain and lying in wait.
Robert Baker pleaded no contest to first-degree murder and was sentenced to life without parole in July 2023. Christopher Austin, an accomplice, pleaded guilty to second-degree murder and received a sentence of 15 years to life in May 2025. Monica Sementilli was sentenced to life in prison without parole in June 2025 and is currently incarcerated at the Central California Women's Facility.
