Missing evidence, hidden files and incomplete investigations are some of the challenges families of Ivan Milat's suspected victims say they have faced in their quest to find answers.
The family of Keren Rowland, who was found dead after disappearing one night in the early 1970s, haven't given up hope of uncovering the truth about what happened to her.
They believe she may have been the first victim of notorious serial killer Milat and argue if police made the connection early on he could have been stopped much earlier in his lethal campaign.
