Detective Garda Adrian Donohoe was murdered in 2013
Federal agents in the United States are intensifying their investigations into two men suspected of being part of the gang involved in the death of Detective Garda Adrian Donohoe.
A report in the Irish Independent today says that FBI officers are working with US police in appealing for information on the two men, specifically honing in on the Irish community in Boston where the two suspects have been living.
Closer to home, Gardai have been liasing with the PSNI, as well as the FBI as part of the investigation.
The newspaper reports that the Bureau have offered a susbtantial reward for anyone who can provide information relating to the two men. It also says posters have been distributed around Boston and in the Norfolk County areas of Massachusetts.
The two suspects at the centre of the investigation are brothers. Two other men believed to be in the five man gang who were involved in Detective Garda Donohoe's death are currently living in Northern Ireland.
The criminal suspected of being the gunman in the murder is set to be released from prison on motoring offences shortly. The man in his 20s was extradited from the United States last year.
Det Garda Donohoe was murdered as he responded to an armed robbery at Lordship Credit Union on January 25th 2013.
Speaking on the fifth anniversary of the murder last month, Louth Chief Superintendent Christy Mangan said, "The persons involved in this murder have no doubt received logistical and emotional support from their families and friends."
Adrian Donohoe died aged 41, survived by wife Caroline and his two young children. He spent his entire Garda career in Dundalk, rising to the rank of Detective. He resided in Bellurgan.
