An international policing expert believes the brutal death of a Roscommon priest can still be solved, if new witnesses come forward.
Today is the 40th anniversary of the killing of Fr Niall Molloy.
The 52-year-old died in Clara, Co Offaly, on July 8th, 1985, in the home of Richard and Therese Flynn.
Richard admitted hitting him at least twice and was charged with his manslaughter - but he pleaded not guilty and was acquitted.
