Gary Flynn loses appeal against gangland murder conviction

Summary

Gary Flynn, aged 32, of Rossfield Drive, Tallaght, lost an appeal against his conviction for the murder of Seamus Shay O'Byrne, which occurred at the victim's home on 13 March 2009. Flynn pleaded not guilty at the Central Criminal Court. After a nine‑week trial, the jury found him guilty of murder in one hour and forty minutes, and he received a mandatory life sentence on 16 March 2016, imposed by Mr Justice Patrick McCarthy. The prosecution alleged that Flynn, Eugene Cullen and others assisted in the planning, execution and aftermath of the murder, while Garrett O'Brien was the gunman. The Court of Appeal, in a three‑judge panel, upheld Flynn's conviction, stating the trial was satisfactory in all respects and that the evidence against him was more than mere coincidence. The appeal was dismissed by Mr Justice George Birmingham. The article does not mention any subsequent developments.
