Investigators suspected Paul due to his checkered past, obsession with wealth and power, and the inscribed gun found at the crime scene with his name.
They found a .32 caliber automatic pistol inscribed with 'love Paul,' Cheryl's purse with $35, two .25 caliber shells, and two unfired .25 caliber rounds.
Multiple neighbors heard gunshots but did not call the police, which is a common but concerning behavior in such situations.
Christina Cromwell took out a life insurance policy on Marlon just two months before his death, suggesting a motive of financial gain.
Layla started trembling and could not get her hands to be steady, indicating a strong emotional response.
Layla described Paul as volatile, moody, and violent, with incidents of physical abuse and attempts on her life.
Alan Halverson implicated Paul Perveler, stating that Paul confessed to killing Marlon Cromwell while they were drunk.
Paul was found guilty on two counts of first-degree murder and one count of attempted murder, while Christina was found guilty of one count of first-degree murder.
Paul's death sentence was commuted to life in prison, making him eligible for parole as early as 1984.
Christina revealed that Paul attempted to have his parents murdered during a trip to Mexico and that she was involved in helping him flee after attacking Layla.
When police were called to the scene of shooting at the Castillion Apartments in Los Angeles on April 20, 1968, they assumed the victim, twenty-two-year-old Cheryl Perveler, had been shot in a robbery gone wrong. However, when they began looking into her personal life, they soon realized Cheryl’s killer could have been much closer to home.
In most cases of individual murders, detectives always look at the spouse first, and in this case, there was a lot to look at. Cheryl had recently married Paul Perveler, a former Los Angeles Police officer with a checkered past and an obvious obsession with wealth and power. Yet the more they investigated Paul Perveler, the more detectives began to suspect they didn’t have just one murder on their hands, and it was starting to look like Cheryl’s death was the culmination of a larger and far more shocking conspiracy than anyone had expected.
