The man who is missing for eighteen years is already "frozen in time", sad people are now hearing his funeral.
Aengus & Gussie & amp; Shanahan disappeared, at the age of 20, on February 11, 2000.
Gardai announced on October 23 that improvements in DNA technology confirmed that bone fragments discovered at the mouth of the Shannon River, 17 years ago, October 28, 2001, belonged to Gussie.
After the report, Gussie's father Bob said that the news had hit him and his family "as lightning".
Thousands of mourners were killed in the Church of Our Lady of Red on the Ennis Road for the funeral of Gussie, where his cousin, Mrs. Aquinas Duffy, said their family eventually found a closure that would remain one of the most significant cases of missing people in the country.
"He is already frozen at the age of 20, 11 February 2000," said Mr. Duffy.
"There is a sense when one disappears throughout his family, we are frozen in time, trapped in this particular time period, unable to move for that day, Gussie is really free."
Mr. Duffy, who founded the missing.ie web site after Gussie's disappearance, said: "We have been talking about (Gussie) and we have been making appeals for almost two decades, yet we are here this morning and we are very grateful for having this moment today, where we can put Gussie to rest.
"It was 18 years old, looking for answers, appealing, and desperately trying to get information that would end the search. Finally, Aengus can get a Christian funeral with his mother, Nancy.
"There are still many families here, and in some cases there are people who have answers that can stop searching."
The Bunratty Search and Rescue Service, a volunteer unit that discovered Gussie's partial skeletal remains, had members attending emotional mass.
Garda has been involved in the case, and has also been involved in search and rescue organizations, as well as many families of other missing persons.
Mr. Duffy told those who are still looking for their loved ones to never give up hope.
"The fact that we are here shows that impossible is really possible," he added.
Gussie's mother, Nancy, died in 2016, still resorting to reports of the youngest of her four children she has always loved dancing the waltz.
Gussie's brother, Roibeard Shanahan, told the sadness that his family "doubts" that his late mother helped them find Gussie.
"Today we gather to erase the negativity, sadness and sadness that has been around (Gussie) over the past 18 years, but rather to fill it with love, positivity and celebration of our lives," he said.
He described his little brother as a "good character, friendly, faithful and hard-working … a child of our family whom we all loved."
Mr. Shanahan said that Gussie "loved" spending time on his relatives in Co Kerry during the summer holidays.
"Gussie has always seen what is good for people, and unfortunately, it has sometimes led him to make a bad judgment about people and situations, as my father has said, sometimes he has gotten him to a few remnants," said Mr. Shanahan.
Gardai conducts a comprehensive review of Gussie's disappearance investigation and says they keep an open mind about the circumstances of his case.
"One thing we want to do today is that people remember that Aengus was not just a picture of a boy in the missing poster, he was 20 years more, which we were pleased with as a family sharing it," said Roibeard Shanahan .
"You're missing your brother, now rest and enjoy the waltz with your mom," he added, greeted by the mourners.
Finally, before Gussie's coffin was taken from the church to a resting place, along with his beloved mother, a collage of valuable family photos and home videos by Gussie with "Foto" singer Ed Sheeran appeared on the screen as a "soundtrack".
Emotional video holdings ended in Sheeran's closing words: "Wait for me to come home."
