A man found guilty of the sexual assault of two women at knife point in a Vernon Burger King in 2005 may never see the light of day again.


At his sentencing hearing in Vernon Thursday, Raymond Mark Simpson was labelled a dangerous offender and handed an indefinite prison sentence.


Vernon Crown Prosecutor, Howard Pontious, says the dangerous offender order is not very common in Canada.


"This is a very rare order. It's not made very often," says Pontious.


"It's only something that occurs when the crown can show that an accused can't be reasonably managed in the community in the foreseeable future."


Pontious says according to a psychologist who testified in the case, there are about 396 dangerous offenders in the prison system and only 15 out on parole.


"The odds are most dangerous offenders don't get out and if they do get out, it's very late in life."


He says Simpson has an out of control cocaine problem and a long history of violent sexual assaults.


According to court documents, Simpson has been convicted twice previously for violent rapes in Ontario dating back to 1991.


He received two years for the first offence and eight years for the second.


"His parole on the second offence expired in April of 2005 and in October of that year, he's attacking these two young girls at a Burger King in Vernon at knife point."


During his trial Simpson, 41, changed his plea from not guilty to guilty.


He changed his plea after one of the two girls in the case testified Simpson had threatened them at knife point, tied their hands behind their backs and cut their clothing. The women were also forced to perform oral sex on the accused.


The woman testified she thought she was going to die and prayed for her life. She also said the other victim begged the accused not to kill them.


He pled guilty to eight separate counts, including sexual assault with violence, forcible confinement and robbery.
