Relatives and friends of 17-year-old Jack Kennedy followed the cortege as it travelled through Athy in County Kildare ahead of his funeral at St Michael's Parish Church.The solemn procession in the historic market town was watched by Garda officers after the crash in the early hours on Sunday at junction three of the M9 motorway.The five teenagers died after the car they were travelling in was driven the wrong way down the road and was involved in a head-on collision with another car.Funerals have already been held for four youngsters who died in the crash - Joey Carthy, 15; Alex McCarthy, 16; Kamil Pustkowski, 17; and Jeremy O'Brien, 18.Three sisters and a young boy from the same family, who were in the other car, were left with serious injuries. They had been travelling to the airport to go on holiday.At Jack's funeral, his mother Sarah apologised to the family in hospital, saying: 'Five young boys made a bad choice. Five young boys paid the ultimate price. Five families lost their babies. Five families got a life sentence. May they all rest in peace.'Secondly, we all want to send our deepest, heartfelt apologies to the families who were injured. You are all in our thoughts and our prayers. We pray to God that you all make a full recovery and once again, we are sorry.'

It's also true of actions. Our actions can hurt people, and our actions can heal people.'In all those situations, we're responsible for the words that we use, and above all, we're responsible for the actions that we take.'He said the feeling in the parish after the crash was 'one of shock, confusion, disbelief, and above all, anger'.'Anger is a very dangerous emotion, and when it starts to curdle and get going in the community, anything can happen,' he said.'When you watch social media and you watch the responses and you hear what people are saying, that's the result of bad actions and very often, then, in all of that, there's so much hurt created for the family.'Sarah put it so well, she doesn't wish any of you to walk in her shoes, to have to bury her son. There's no great future in all of that.'And again, as I say, the dust has settled somewhat, and the week has passed by, there is something I want to say, and especially to Jack's friends, and it's this – if you're considering continuing this criminal activity, will you please stop?'Just one word, stop. Because this is the end of it.'This is a family broken, and the consequences of that will happen to you too, for you yourself, for your families, the communities in which you live in, and then you'll have the innocent victims, like the people who are in hospital trying to recover.
