The beauty industry lost a titan on January 23, 2017. Most people remember Fabio Sementilli as "Big Daddy," the charismatic Wella executive with the infectious laugh who mentored thousands of stylists. But for those following the headlines in 2025, his name is now inextricably linked to a "slaughter" in a Woodland Hills backyard.
Justice took eight years. Eight years of legal delays, COVID-19 backlogs, and a family torn apart by a betrayal so deep it feels like the plot of a noir film. In June 2025, a Los Angeles judge finally closed the book on the criminal trial of Monica Sementilli.
She was sentenced to life in prison without the possibility of parole.
The Day the Music Died in Woodland Hills
Fabio was sitting on his patio. It was a Monday afternoon. He was 49, at the peak of his career, watching TV and relaxing at home. Then, two men in hoodies jogged up.
One was Robert Baker. He wasn't just some random thug. He was Monica’s lover—an ex-porn actor and racquetball instructor she’d met at the gym. The attack was swift and brutal. Fabio was stabbed seven times. The wounds hit his femoral and carotid arteries. He didn't stand a chance.
The scene was staged to look like a robbery gone wrong.

Investigators found the house ransacked, but something didn't click. Fabio’s $8,000 Rolex was still on his wrist. Who leaves a Rolex during a "robbery"? Not professional thieves. It was the first of many cracks in the story Monica tried to tell.
Monica Sementilli: The "Architect" of the Crime
For months after the murder, Monica played the part of the grieving widow. She posted tributes on social media. She held a wake where she wept for the man she’d been married to for 20 years.
But behind the scenes? She was allegedly plotting to collect a $1.6 million life insurance policy.
Detectives were watching. They caught her on camera meeting Baker in secret. DNA evidence eventually linked Baker to the scene—he’d actually cut his own finger while stabbing Fabio, leaving his blood behind.
- The Motive: Pure greed and "lust," according to prosecutors.
- The Plan: Monica allegedly left the back door unlocked and texted Baker when the coast was clear.
- The Accomplice: Christopher Austin, a former probation officer who acted as a lookout.
During the 2025 trial, the defense tried to paint Monica as a victim of Baker's obsession. Baker even took the stand and claimed Monica had nothing to do with it. "I murdered him because I wanted her," he told the court.

The jury didn't buy it.
They saw the text messages. They saw the timeline. They saw a woman who wanted the money and the lover, but not the husband who provided the lifestyle.
A Legacy Beyond the Trial
It's easy to get lost in the "true crime" aspect of this. Honestly, it's a tragedy that the murder has overshadowed the man. Fabio Sementilli was a legend in the hair world. He started as a kid sweeping floors in a Toronto barbershop and worked his way up to Vice President of Education at Wella.
He called everyone "brother" or "sister." He championed the #ICAN movement, pushing stylists to see themselves as artists and entrepreneurs.
His daughters, Gessica and Isabella, faced a nightmare. At the 2025 sentencing, they were caught in an impossible position—mourning a father they adored while watching their mother be led away in handcuffs. Isabella told the court she wouldn't let the tragedy define her.

What the Verdict Means for the Industry
The conviction of Monica Sementilli brings a "horrible kind of peace," as one of Fabio's sisters put it. The beauty community, which Fabio spent decades building, has largely moved toward honoring his professional contributions rather than focusing on the sensationalist details of the trial.
The #ICAN scholarship still exists. His mentorship videos are still watched by young stylists. The "Big Daddy" persona lives on in the salons where he once taught.
Actionable Insights for Following Case Developments
If you are following the aftermath of the Fabio and Monica Sementilli case, here is what you need to know about the current status of the legal fallout:
- Sentencing Finality: As of June 2025, Monica Sementilli is serving life without parole. There is no "out" for her.
- The Accomplices: Robert Baker is also serving life. Christopher Austin, who cooperated with the state, received a sentence of 16 years to life.
- Industry Impact: If you are a hair professional, the Fabio #ICAN Scholarship remains the primary way to engage with Fabio’s legacy. It focuses on continuing education, which was his greatest passion.
- Victim Support: The case serves as a grim reminder of the importance of domestic violence and conspiracy investigations. The LAPD Robbery-Homicide Division's work on this case is often cited as a masterclass in breaking down "electronic footprints" like WhatsApp messages and cell tower pings.
Fabio Sementilli wanted to be remembered for how he made people feel. While the court records will always hold the details of his death, the salons of the world hold the memory of his life.
