The tragic garda was shot during an armed robbery of a Louth Credit Union on 25th January 2013.

Aaron Brady from County Armagh appeared before a special sitting of Dundalk District Court last night in relation to the murder.

I met Detective Garda Adrian Donohoe four months before he was murdered. He was a real gentleman. I’ve done dozens of stories about his case in the last five years. I didn’t want him to be forgotten about. Today’s a huge day for Dundalk and #gardai and, above all, his family. RIP pic.twitter.com/Van2DgrO4B

Over the years as then NE Corr I met Adrian Donohoe at many scenes. He was always an absolute gentleman, polite and cheery. An outstanding #Garda. A huge loss to his family, community & force. Thinking of them tonight.

Earlier this year, the FBI had placed wanted posters in the Boston areas of Dorchester and Quincy, where it was believed the three suspects were on the run.
