Mark Andre Tomas Navarrete was sentenced to two consecutive life sentences without the possibility of parole after a jury convicted him of murdering his parents for their estate.
The 47-year-old Elk Grove man was found guilty on October 16, of two counts of first-degree murder in the June 28, 2024 killings of his mother and father. Judge Michael Bowman handed down the sentence after jurors also determined Navarrete had committed multiple murders and that financial gain was the driving motive.
Principal Criminal Attorney Aaron Miller of the Homicide Unit said Navarrete stood to inherit half of his parents’ estate when he carried out the killings. The defendant had been running fake investment schemes targeting friends and relatives, promising to repay their money with exorbitant interest rates. Investigators determined his parents had stepped in to repay other family members for debts he owed, fueling his resentment toward them.
That resentment became a calculated murder plot. Navarrete drove from his Elk Grove home to his parents’ neighborhood and left his vehicle several blocks away. He disguised himself with a mask and gloves, then rode a kick scooter to their house to avoid detection.
He slipped through a side gate to bypass the front porch Ring camera and met his parents at the backyard entrance. Once he got them into the garage, Navarrete struck both of them on the head with an object before strangling them to death while facing them.
After the killings, he fled in his parents’ car, parked it a short distance from his original parking spot, and used the scooter to return to his own vehicle.
The cover-up took an even darker turn. Navarrete texted his dead parents to ask whether they wanted to come over for dinner, part of what prosecutors described as a chilling attempt to cover his tracks.
When his sister grew concerned because she could not reach them, he drove to their home with his own children and staged the discovery of their bodies. The performance was meant to deflect suspicion, but investigators soon uncovered crucial evidence that unraveled his elaborate ruse.
Detectives discovered the kick scooter in Navarrete’s garage. DNA testing found his DNA underneath his mother’s fingernails, evidence of her struggle against him. The Elk Grove Police Department also used Flock cameras and other traffic surveillance footage to track his movements on the day of the killings, building a timeline that contradicted his claims.
The case combined financial fraud, familial betrayal, and the manipulation of his own children into a gruesome deception. Prosecutors emphasized that Navarrete did not merely kill for money but constructed an elaborate performance to conceal his crimes, using his children as unwitting props in the staged discovery.
The double murder has left extended family members grappling with multiple layers of betrayal, from the fraudulent investment schemes that preceded the killings to the final act of bringing children to a crime scene.
Navarrete will serve his two life sentences consecutively, ensuring he will never be released from prison.
