Should killers be denied parole if they refuse to reveal location of victims' bodies?

Almost 30 years ago, Helen McCourt was murdered at the age of 22. Her killer has never revealed where her body is.

On Friday, 'Helen's Law' will be considered in Parliament. It proposes to deny killers parole if they don't reveal where victims' remains are.

Jayne McCubbin has been speaking to Helen's mother Marie who has led the campaign.
