A documentary about the disappearance of Mary Boyle (pictured), the 6-year-old who went missing in 1977, has been released on YouTube.
Mary Boyle: The Untold Story was written and directed by investigative journalist Gemma O'Doherty who supports the campaign by Mary's twin sister Ann Doherty and singer Margo O'Donnell for a new investigation into Ireland's longest missing person case.
On March 18, 1977, the little girl from Kincasslagh went missing while visiting her grandparents at Cashelard, near Ballyshannon. She has never been found.
Ann and members of the Families for Justice campaign claim that there was political interference in the initial investigation.
Ann and Margo have given the gardaí the names of people they believe should be interviewed.
The documentary, which was released on Monday night, includes interviews with Ann and Margo as well as two retired garda detective sergeants who were involved in the original investigation, Aidan Murray and Martin Collins.
Felt” let down”
Speaking on Ocean FM on Tuesday morning, Margo said she and Ann, who have met Enda Kenny and travelled to the USA as part of their campaign, feel "let down by the Irish government and the justice system".
She added, "We didn't get help from the Irish government or the justice system so what else were we to do? We're embarrassed to have to go further afield."
They hope the public will support their campaign and put pressure on the authorities to open a new investigation, Margo explained.
"All we want is Mary's remains. I want that person out there or the people who are with them, to tell us where she is so that we can find her remains and give her a proper burial."
They are already very encouraged by the response.
“We - Ann, Gemma and myself - have received a lot of texts, emails and calls, from all over Ireland and the UK, the US and even one from South Africa,” she said.
