A State apology was given by Jim O'Callaghan on Tuesday to the family for failures in the criminal justice system that exposed Mr O'Farrell to danger. Mr O'Callaghan also announced a review into bail and suspended sentences. The driver of the car, Zigimantas Gridziuska, failed to remain at the scene. The Lithuanian national had a number of previous convictions, including theft and drug offences. He surrendered himself to gardaí the following day. In February 2013, Gridziuska was prosecuted for dangerous driving, causing Mr O’Farrell’s death. He was acquitted of that charge by direction of the trial judge, and, under the law at the time, a lesser charge of careless driving was not open to the jury. The Dáil heard on Tuesday that he has since returned to Lithuania. However, Shane's sister said that while the apology from the State was a "long time coming", there are "still unanswered questions". "It is a hugely significant day, but it was also a very sad day because it is the State accepting that what happened to Shane should never have happened," Hannah O'Farrell told RTÉ's Morning Ireland on Wednesday. "That is something we have known ourselves for years, but I suppose it is different when the Minister of Justice is standing up and apologising for that on behalf of the State." She added that if there had been an "apology forthcoming in the early years and we were provided with the answers that we were seeking, then that would have really helped our journey of grief". "We just want to be a normal family and grieve in private, and we had to over the past number of years to get answers, engage with various state agencies, who treated us very badly in the process and also engage with the media, who helped us uncover some of the information." "It has been a very long time coming, and I hope there is a learning from that on behalf of the State," she added. However, Ms O'Farrell said there are unanswered questions, especially in regards to a Section 101 report that has not been provided to the family, which they hope will give them the "closure to grieve". It is true that we do not know all the circumstances surrounding Shane's death, and I'd say a part of that is because we did all of this ourselves, and no state agency was coming to us telling us what happened. So there are unanswered questions. "That does not diminish how significant the apology is because the apology is accepting that this shouldn't have happened based on the information that is known," she said. "But in terms of unanswered questions, we engaged with the Gsoc process as part of our garda complaints, and the product of that was a Section 101 report which had been ordered by the then minister of justice, Alan Shatter, in the public interest. "And that public interest report in our view should just be published on the website for the public, but it hasn't been provided to us and they're our complaints and we know it has been provided to named individuals, it's difficult to see why named individuals can look at that report when we can't and they're our complaint." Shane was 'ready to enjoy life' Speaking about her brother, Ms O'Farrell said: "I only realise now that Shane was only a child when he was killed. He had all the normal hopes and dreams for a 23-year-old." Ms O'Farrell said her brother had just handed in his thesis on the Friday before he was killed and had sent a text with the Martin Luther King Jr quote 'Free at last' to the family after submitting it. She said he was just "ready to enjoy life." "He was ready to do a bit of travelling, watch a bit of rugby and have a couple of months of happiness and peace and get away from the books," Ms O'Farrell said. "I would often think about where he would be now and what he would be doing now, and all the things and events that he has missed and the things we have missed because of him and the big absence that he is in our society. "We remember him every day, but especially on days like yesterday and just how significant his loss is for us," she said.
