A former male performer (Rob Baker) has been found guilty for murder. Now, his girlfriend will be going to prison for the same crime.

Monica Sementilli, the widow of internationally known hairstylist Fabio Sementilli, has been found guilty of first-degree murder and conspiracy to commit murder in a Los Angeles courtroom, following a lengthy 10-week trial that detailed a plot driven by financial gain and personal betrayal.

The Los Angeles County District Attorney’s Office announced the jury’s decision on Friday, April 11th, confirming that Monica Sementilli, 51, was convicted of murdering her husband in 2017, with special circumstance findings that elevate the case to a potential life sentence without the possibility of parole. The special circumstances include committing the murder for financial gain and carrying it out by means of lying in wait.

“This was a cold and calculated crime motivated by greed and betrayal,” said District Attorney Nathan J. Hochman. “Today’s verdict ensures that those responsible for this ruthless act will be held accountable.”

Monica Sementilli and her lover, Robert Louis Baker (porn’s Rob Baker), were both charged in the killing of 49-year-old Fabio Sementilli, who was found stabbed to death at the couple’s Woodland Hills home on January 23, 2017. According to prosecutors, Baker ambushed Fabio while he sat on the patio, stabbing him multiple times before fleeing the scene in the victim’s Porsche. The car was later found abandoned several miles away.

Rob Baker, a former adult film performer and talent manager, previously pleaded guilty to first-degree murder with special circumstances. He was sentenced to life in prison without parole. DNA evidence tying him to the crime scene, as well as to the stolen vehicle, was instrumental in securing convictions. His DNA was linked through a prior conviction for lewd and lascivious conduct with a minor, which required him to register as a sex offender.

Though Baker initially tried to shield Monica Sementilli during his own legal proceedings—testifying that she had no role in the planning or execution of the murder—the jury found otherwise. Prosecutors successfully argued that the two conspired to kill Fabio, motivated by an affair and a desire to collect life insurance money.

“This verdict is the result of years of tireless investigation and prosecution,” said Hochman, who praised Deputy District Attorneys Beth Silverman and Heather Steggell for their work. “They painstakingly put together each piece of this murder puzzle to overcome the lies and deception.”

A third man, Christopher Austin, was also implicated in the murder. He pleaded guilty to second-degree murder and is currently serving a sentence of 16 years to life.

Monica Sementilli now awaits sentencing, scheduled for June 23 at the Clara Shortridge Foltz Criminal Justice Center in downtown Los Angeles. Based on the special circumstances verdict, she is eligible for a sentence of life in prison without the possibility of parole.
