Davis was convicted of two murders that were not related to the infamous Tate-LaBianca murders by other Manson family members.
In October, a three-member parole panel voted to grant Davis release at his 27th parole hearing since his conviction in 1969. That decision had to be reviewed by the entire board over a 120-day period, which ends Monday.
Lace wrote a letter to Gov. Brown asking him to reverse the board's decision, saying that Davis has not expressed genuine remorse for his crimes.
Davis and Steve Grogan were convicted for the murders of musician Gary Hinman and stuntman Donald "Shorty" Shea in 1969. Grogan was paroled after he led police to the location of Shea's body in 1985.
If the entire board accepts the panels parole recommendation, Gov. Brown has 30 days to approve or reject it.
