All about Monica Sementilli explored

On January 23, 2017, Fabio Sementilli was found brutally stabbed to death in his home. This initially appeared to be a case of robbery. However, as the investigation progressed, suspicion began to fall on his wife, Monica Sementilli.
As per CBS News, Monica Sementilli was put on trial for her role in the murder of her husband, Fabio Sementilli, in January 2025. During the trial, prosecutors said that Monica had planned the entire plot with her lover, Robert Baker.
As reported by CBS News, Deputy District Attorney Beth Silverman stated:
"It's very obvious that the defendant, along with her lover, murdered Fabio Sementilli along with assistance from Christopher Austin, committed for financial gain as well as for other motivations -- in other words, for their future together."
As per an article in People, dated April 11, 2025, during the trial, on January 23, 2017, prosecutors said Robert Baker and his accomplice, Christopher Austin, arrived at Fabio Sementilli's home in Woodland Hills. They silently entered and attacked Fabio from behind while he was alone watching television in the backyard.
Fabio was reportedly stabbed seven times in the neck, chest and thigh, severing his femoral and carotid arteries. After the murder, Baker and Austin searched the bedroom, stole the DVR from the garage, and drove off in Fabio's 2008 Porsche 911, which was found abandoned two days later about five miles away.
Austin, who has admitted to second-degree murder, testified that Monica purposely left the door to the house open and that Baker had said Monica wanted to eliminate Fabio.
As reported by People, Austin said:
"Everything he did he did after he got a text message, which told me he was talking to her via text message. I did not hear him talk to her on the phone ... but everything happened in sequence.”
Baker, who pleaded no contest to Fabio's murder charge in 2023, insisted that Monica had nothing to do with the killing. As per People, he said:
“I murdered him because I wanted her. She had nothing to do with it.”
