The trailer for a forthcoming documentary, Mary Boyle: The Untold Story, written and directed by investigative journalist Gemma O’Doherty, about the disappearance of Mary Boyle in Donegal in March, 1977.

It includes interviews with retired sergeant Martin Collins and former detective inspector Aidan Murray (top) who recall a phone call made by a politician to gardaí, during the investigation into Mary’s disappearance, and how the phone call led to certain people not being arrested or questioned.

Mr Murray remembers how, during one interview, he “suddenly got a wee nudge” from his superior officer and was effectively told to “ease off” while questioning a man.

Mary Boyle: The Untold Story will be available in full in the coming weeks.
