A convicted cop killer who admitted to sexually assaulting — and, in one case, raping — his younger sisters has little to no remorse for his actions, a judge said Friday.

John Miller was sentenced on four historical sexual charges after entering guilty pleas earlier this year.

"It may be the case that Mr. Miller, in his own muddled way, thinks he has done the right thing," Kamloops provincial court Judge Chris Cleavely said in sentencing Miller to four years in jail.

The 63-year-old admits to sexually abusing four of his sisters over a period of years in the 1960s and 1970s.

Court heard the abuse only stopped in 1974 when Miller was sentenced to hang after killing a Mountie in the Lower Mainland. He shot Surrey RCMP Const Roger Pierlet in 1974, after he was pulled over for a routine check.

His sentence was commuted to life when the death penalty was abolished in 1976 and he was eventually released on parole in 1997.

Following his release from prison, he moved to Kamloops.

In their victim-impact statements read in court last month, Miller's sisters described him as "a bogeyman" and said the years of abuse have stayed with them forever.

Court heard Miller would hide under the beds or in the closets of his younger sisters at night and would attack them in their beds.

Sometimes he would carry the girls to his own room.

The attacks also sometimes occurred in the family's washroom, where Miller had set up a peep-hole so he could see who was using the bath.

The attacks ended when Miller was incarcerated, but he is also alleged to have molested a niece — the daughter of one of his original victims — after being granted parole in the 1990s.

No formal charges have been laid in relation to that allegation, but the incident was referenced in a report by the National Parole Board.

The Crown had been seeking a jail term of up to six years, but Cleavely gave Miller credit for entering guilty pleas and preventing a trial.

In addition to the prison sentence, Miller will also have to register as a sex offender and submit a sample of his DNA to a national criminal database.
