Wife in deadly love triangle with racquetball coach and her hair mogul husband gets life sentence
The wife of a celebrity hairstylist will spend the rest of her life in prison for having her lover kill her husband in what was supposed to appear as a home invasion robbery gone wrong.
Monica Sementelli, 53, was sentenced to life without parole Monday for the brutal stabbing of her husband, Fabio Sementelli, 49, in their Woodland Hills home eight years ago. A jury in April convicted her of murder and conspiracy to commit murder for masterminding the slaying on their Woodland Hills deck, where one of their daughters would later find him wounded in a pool of blood.
Los Angeles County Superior Court Judge Ronald Coen, before pronouncing sentence, rejected a bid by Sementelli's legal team to get her sentenced to 25 years to life in prison.
Fabio Sementelli suffered multiple wounds to his face, jawline, neck, chest and thigh and the fact that his $8,000 Rolex watch was left on his wrist when he was killed left detectives puzzled.

Blood from the crime scene was soon linked to Robert Baker, a convicted sex offender and former porn star who began an affair with Monica Sementilli after serving as her racquetball coach at a West Hills fitness club. While prosecutors have painted Sementilli as the "mastermind" behind the slaying, as she stood to gain $1.6 million in life insurance payouts, Baker took the stand during the 2 1/2-month trial and insisted he killed the hair mogul for love.
'I murdered him because I wanted her,' Baker testified during her trial. 'She had nothing to do with it."
Baker was previously convicted of Fabio Sementilli's murder and also sentenced to life without parole.
During Sementilli's trial, L.A. County Deputy Dist. Atty. Beth Silverman presented video evidence that showed Monica Sementilli watching a live feed of the area shortly before the attack to ensure Baker had a clear path to her husband. Mitzi Roberts, a veteran homicide detective with the Los Angeles Police Department, also testified that Sementilli and Baker exchanged 95 messages through an encrypted messaging app called Viber on the day of the killing and 180 messages the day before.
While Sementilli denied all wrongdoing and publicly grieved her husband — an executive at the hair care company Wella — she was involved in a torrid affair with Baker. The pair sexted during her husband's funeral, according to Silverman, who said the the new widow even sent nudes to Baker during the service in Toronto.

Baker's accomplice, Christopher Austin, also testified for the prosecution and insisted Baker told him Sementilli had directed her husband's murder. Austin, a former Oregon probation officer, said he never spoke to Monica directly, but Baker made clear his lover wanted her husband "gone."
'Everything he did, he did after he got a text message, which told me he was talking to her via text message.' Austin testified. 'I did not hear him talk to her on the phone ... but everything happened in sequence.'
Defense attorney Leonard Levine insisted, "Adultery is not murder. ... Everything she did was to protect the affair, not to cover up the murder." He called Baker a ``Svengali,'' saying that Sementilli made the ``biggest mistake of her life'' in becoming involved in an extramarital affair with him.

Testimony begins in first-degree murder trial
Jun. 23—Testimony began Monday in the trial of a South Valley man who prosecutors say fatally shot 30-year-old Anjel Varela after conspiring with others to rob the victim outside a Northeast Albuquerque apartment complex. Bobby "Littles" Lopez, 30, is accused of shooting and killing Varela in his car after a robbery coordinated between Lopez, another woman and Varela's passenger went awry. Lopez has been charged in 2nd Judicial District Court with first-degree murder, armed robbery, conspiracy to commit armed robbery and possession of a firearm by a felon. The trial is scheduled through Friday before Judge Emeterio Rudolfo. Authorities say that Lopez is a known member of Los Padillas, a South Valley gang with a longstanding history of homicide, drug trafficking and other offenses. Lopez's attorney, Sandra Gallagher, told jurors Monday that three key witnesses, Danielle "Foolish" Cordova, Brianna "Shorty" Garcia and Delilah Lopez, cut a deal with the state in exchange for reduced charges in Varela's killing. "When you make a deal with the state, you have to throw someone into that volcano," Gallagher said in opening statements. Garcia agreed to testify against Bobby Lopez when she pleaded guilty to numerous prior felony charges as well as second-degree murder, armed robbery and conspiracy, according to her 2023 plea agreement. Cordova also agreed to testify when she pleaded guilty to armed robbery and conspiracy in 2023, court records show. Similarly, Delilah Lopez's murder charges were dropped after entering a plea agreement in which she agreed to testify. Delilah Lopez is charged with armed robbery and conspiracy. All three had originally been charged with an open count of murder, robbery and conspiracy, the same charges that Bobby Lopez originally faced. Assistant District Attorney Christine Jablonsky said in opening statements that Garcia, spiteful over being sold "bad heroin" by Varela, orchestrated the armed robbery and enlisted Bobby Lopez. Garcia asked Varela for a ride and messaged Cordova on Facebook about the pair's whereabouts as they drove around Albuquerque, Jablonsky said. Garcia asked Varela to pull over at the Skyline Apartments on Louisiana and Mountain so she could use drugs, at which point Bobby Lopez, his girlfriend Delilah Lopez and Cordova parked nearby after tailing the pair across Albuquerque, Jablonsky said. Bobby Lopez posed as a member of Garcia's family and asked Varela to sell him drugs, she said. Once in the car, Bobby Lopez grabbed Varela's gun from his lap while Garcia took $80 and a dab kit, used for smoking cannabis, from the car, according to a criminal complaint filed in Bernalillo County Metropolitan Court. Bobby Lopez then shot Varela in the back and he and Garcia left him slumped over and bleeding in his vehicle, Jablonsky told jurors. Varela's girlfriend, Clarissa Sanchez, took the stand Monday and tearfully recalled finding his body. "I put my hand on his chest, I felt how cold he was and I knew he was dead," Sanchez said.
