Summary
Monica Sementilli lived a double life—suburban wife by day, murder conspirator by night. In this chilling true crime breakdown, we follow the brutal 2017 murder of celebrity hairstylist Fabio Sementilli, a man beloved in the beauty world but betrayed in the worst way by the woman he trusted most.
Fabio was ambushed outside his Woodland Hills home, stabbed repeatedly in the neck and torso by Robert Baker—Monica’s secret lover and a former porn actor. Monica had allegedly left the door unlocked, paving the way for the killers. The motive? A $1.6 million life insurance policy and the promise of freedom from divorce.
Baker testified he acted alone out of love. But a jury didn’t buy it. The prosecution called Monica the “prime mover” of the plot, arguing that Baker didn't have the brains for such a cleanly executed crime. They believed Monica orchestrated every detail—down to ensuring her daughter would be the one to find Fabio’s mutilated body.
She’s now serving life without parole. Baker is also doing life. The third accomplice, Christopher Austin, got 16 to life. And Monica’s family? They still insist she’s innocent.
This is a story of greed, lust, betrayal, and a horrifying end to what was once considered a fairy-tale life. Buckle in—this case gets dark.
