Members of the O’Dwyer family thanked the public for their support in recent days and have now appealed for privacy.
His family said while they were “dealing with the unthinkable and devastating heartbreak of Tim’s loss, they wished to thank their family, friends and neighbours for the incredible outpouring of kindness and support at this incredibly difficult time. We ask now for privacy”.
Senator Martin Conway, who knew the family said he was heartbroken for the O’Dwyer family.
“The whole community are behind them to support in any way they can. It has put a huge dampener on the whole community. I would appeal to people to respect the family’s appeal for privacy”.

“Tim played with us from a very young age. He was a well-liked and hard-working player within our club. He will be greatly missed by everyone who knew him.”
The Department of Foreign Affairs confirmed to the Mirror they were providing consular assistance to the family and were working with “the O’Dwyer family on efforts to get Mr O’Dwyer’s remains repatriated”.
