The detective who snared convicted double murderer Bill MacDowell has vowed to confront him behind bars to find out where he buried his victims.
The 81-year-old will die in jail after being handed a life sentence last week for killing his lover Renee MacRae, 36, and their three-year-old son, Andrew.
Their bodies have never been found, causing anguish for the MacRae family after the double killing in November 1976.
