CONVICTED GARDA MURDERER Aaron Brady has been charged with perverting the course of justice and conspiring to persuade a key State witness not to testify during his trial for murdering Detective Adrian Donohoe.

Brady, 31, of New Road, Crossmaglen, Co Armagh, had denied capital murder for shooting Detective Garda Donohoe dead during a robbery at Lordship Credit Union in Co Louth on 25 January 2013.

However, he was handed a life sentence after being found guilty at the Central Criminal Court in August 2020.

Following an investigation by the Garda National Bureau of Criminal Investigation (NBCI), Brady and two other men appeared before Judge Bryan Smyth at Dublin District Court yesterday.

The court heard a “substantial file” had been sent to the Director of Public Prosecutions (DPP).

He is accused of conspiring with co-defendant Dean Byrne to persuade Daniel Cahill, a prosecution witness in his trial, not to give evidence, to pervert the course of public justice, between 8 April and 22 June 2020. During the trial, which ran from January to August, he testified he overheard Brady say he shot a garda.

Brady has a second charge that on a date unknown between 20 February and 7 May, 2020, he video-recorded the playing of a video-recorded witness interview between Ronan Flynn and members of An Garda Síochána, thus embarking upon a course to pervert the course of public justice.

Both charges are contrary to Common Law and can, on conviction, result in unlimited fines and jail sentences.

NBCI Detective Sergeant Brian Quirke told Judge Smyth that Brady made no reply to the charges after his arrest yesterday morning.

The DPP directed that he would face trial on indictment in a higher court.

Brady did not address the court. His barrister successfully applied for legal aid on his behalf.

Detective Sergeant Quirke said there was no objection due to the seriousness of the case.

Prosecutors must complete a book of evidence before he can be sent forward for trial.

Judge Smyth remanded him in custody to appear via video link on Friday.

The court heard Dean Byrne, 29, from Cabra Park, Phibsborough, Dublin, “gave no reply to charge”.

NBCI Detective Kevin Lawless said the DPP directed that Byrne will also be tried on indictment. He objected to bail due to the seriousness of the case.

He alleged a contraband phone was recovered from his cell in Mountjoy Prison with five recovered WhatsApp exchanges.

It was alleged there were message threads and voice and audio messages to an anonymous contact with threats and offers to intimidate Dean Cahill.

It was alleged the witness was referred to as a rat, and his statement and the book of evidence were mentioned.

The court heard there was an incoming message that said, “I’ll find him”, followed by a money symbol and a wink emoji.

Detective Garda Lawless alleged Byrne replied with a voice message mentioning the shooting and calling the witness a “smelly bastard “c**t”.

The court heard an incoming clip said, “I will go look for him; I know a person who probably knows where he is”.

Messages were forensically extracted from Facebook Messenger with references to Dean Cahill on 11 April 2020 and an effort to “get him to stop”.

Detective Garda Kevin Lawless alleged that Dean Byrne was a “conduit” between Aaron Brady and others. The detective described him as innovative and adaptive, using a contraband mobile phone.

Judge Smyth refused to grant Byrne bail and remanded him in custody pending his next appearance via video link on Friday. He was also allowed legal aid following an application by his solicitor.

The third defendant, Glen Holland of Rory O’Connor House, Hardwicke Street, Dublin 1, was charged with unlawful possession of a mobile phone in prison from 7 to 28 August 2020.

Detective Garda Paul O’Hara said Holland also made no reply to his charge.

His case is to be dealt with at district court level. The judge granted him bail. Once released, he must sign on daily at a Garda station, not apply for travel documentation, and have no contact with Brady or Byrne, “including by any electronic means”.

Judge Smyth granted him legal aid and adjourned his case until 9 May. None of the defendants have indicated a plea.
