Fifty-three-year-old Daniel Robert Dow is serving an indeterminate sentence after he was convicted in 1998 of beating and choking a woman into unconsciousness and threatening to kill her child.
He also has previous convictions for violent sexual assaults.
The National Parole Board rejected either day parole or full parole for Dow after he refused to detail his sexual fantasies.
The parole board says a psychiatric assessment in July concluded Dow is a moderate-high risk to re-offend both sexually and violently, and instead recommended that Dow first show stability in a minimum-security prison before being considered for release.
The police have named Dow as a suspect in the disappearance of 20-year-old Sherri McLaughlin, who disappeared from Kamloops in 1993, when Dow was on parole for a previous conviction.
Dow has never admitted any involvement and has refused to co-operate with investigators.
The RCMP used forensic evidence to link Dow's car to McLaughlin's damaged bicycle, but he has not been charged in the case.
McLaughlin's body was never found.
