A woman who fought for changes to the Faint Hope Clause has passed away at the age of 75.

Darlene Boyd's teenage daughter Laurie was murdered in 1982 and Darlene fought to keep the men convicted of the crime in prison to complete their sentences.

Laurie was working at the Red Rooster convenience store in Okotoks January 30, 1982, when she was abducted by James Peters and Robert Brown, who raped and murdered her and then set her remains on fire. 

23-year-old Debbie Stevens was stranded a few kilometres from home on December 12, 1981, when Peters and Brown picked her up, drove her out of town, raped and killed her and also set her remains on fire. 

The two men were found guilty of two counts of first-degree murder and the judge handed them life sentences without the chance of parole for 25 years. 

The Faint Hope Clause allowed convicted murderers who've served 15 years of their sentence a chance to have their parole ineligibility reviewed by a jury. 

Peters was able to apply for parole 10 years early which prompted Darlene on her quest to change the law.

Brown, who had been living in Blackie at the time of the crimes, killed himself in jail. 

After years of lobbying, the government made it so people convicted of murdering more than one person could not apply to lower their parole eligibility from 25 years.

The Faint Hope Clause no longer exists for convicted killers. 

A pedestrian bridge in Okotoks' Sheep River Park was named in honour of Laurie Boyd in 2018.

Darlene Boyd passed away on January 3 at the hospital in Vulcan.
