Smyth, who is originally from Artane on the capital’s northside, has been investigated for involvement in the double-cross murder of drug dealer Sean Little. The 22-year-old was lured to Walshestown Road, Balbriggan, where he was murdered late on the night of May 21, 2019, when he was shot multiple times in the head.
As tensions increased in the weeks after this, Smyth fled the country. While he was away he sent associates of Little the results of a bizarre lie detector test which he claimed proved he wasn’t involved in the killing.
Chillingly, however, Smyth’s efforts to prove his innocence were rebuffed by Little’s associates who released a copy of the lie detector report on social media, alongside the picture which had been altered with the words: “You can send us all the lie detectors you want you dirty dog. you’re dead.”
