The Mistress of Hollywood: June Cassandra Mincher

In July, Bill Mentzer was convicted of the first-degree murder of Roy Radin.  Facing a second trial later that year and the possibility of a death sentence, he confessed on December 6, 1991, to the murder of June Mincher.  In exchange for his confession and testimony against Lowe and Pascal, he received life in prison.  He said he'd received $25,000 to kill June Mincher, and that Pascal had told him the Antonelli family did not know it was going to happen. 

Laney Jacobs-Greenberger was convicted of kidnapping and second-degree murder, and was sentenced to life in prison without the possibility of parole.  The judge rejected her claim, according to the New York Times, that she had only ordered a kidnapping for the purposes of extortion and never expected Radin to be killed.

Alex Marti was convicted of first-degree murder and received life in prison without parole.  Lowe was convicted of second-degree murder and aggravated kidnapping resulting in death.  He received life in prison without parole.

Michael Pascal, a paranoid man with wild fantasies about being followed, was arrested in 1993 and arraigned for the Mincher murder.  "When we arrested Pascal," recalls Rick Jackson, "he was shaking like a scared child."  Confused as to how the police had tied the incidents to him, he pled guilty to voluntary manslaughter.  Before going to prison, he died from cancer.

Christian Pierce, too, died in 1993, from a drug overdose.  At the trial, he had recognized Mentzer as the man who had shot him.

In 2004, Mentzer was suggested as a suspect in the long-unsolved series of Zodiac murders in 1968-69 in the San Francisco area.  Zodiac theorists pointed out that that he'd been discharged from Vietnam in 1968, three months before the first of the Vallejo killings, and had gone to California.  Apparently, he suffered from Post Traumatic Stress Disorder for a while.  His circumstances and personality fit a police profile devised at the time, but there was no actual evidence to tie him to the murders.

Given his participation in the contract murders and his apparent need to brag about them, it's unlikely he'd have kept closed-mouthed about pulling off the sensational Zodiac killings.  He doesn't really fit the profile.
