In January, Bruce Davis, 67, serving two life sentences for the 1969 killings of Spahn movie ranch farmhand Donald "Shorty" Shea and musician Gary Hinman at his Topanga Canyon home, had been recommended for parole, the Los Angeles Times reported.
Davis allegedly did not take part in the Tate-LaBianca murders committed by other Manson family members, and while incarcerated at the California Men's Colony in San Luis Obispo earned a master's degree and a doctorate in religion, KABC-TV, Los Angeles reported Monday.
In a letter, Schwarzenegger said he found it troubling Davis, a born-again Christian, said he would be subservient to his wife if released. The governor worried Davis could be too willing to follow the directions of others, KABC-TV reported.
Schwarzenegger said although Davis has made credible accomplishments during his imprisonment, "The first-degree murders for which Davis was convicted were especially heinous because both victims were abused, tortured and mutilated."
