Gardai believe the bodies of a young missing couple - killed on the orders of crime boss Cornelius Price - will never be found.
Detectives suspect about five people know the truth of what happened to Willie Maughan, 34, and Ana Varslavane, 21, but they will never spill the beans.
Officers are convinced Willie and Ana were both murdered at Price's large fortified compound at Gormanston, Co Meath and their bodies incinerated afterwards.
