HUNDREDS of mourners have gathered this morning at the final funeral service of the students who died in the balcony collapse in Berkeley, California at the start of last week.
Lorcan Miller (21) was a third year medicine student in UCD, where he studied alongside Eimear Walsh.
His parents Ken and Sinead are the chief mourners at the service.
Ken Miller broke down as he paid an emotional tribute to his "truly remarkable" son.
"Lorcan was an extrovert who loved life and wasn't afraid to try new things," he told the congregation.
"He threw everything he had into everything he did," he added.
He told those present with stories of his son's life where he was always in charge it organising events- a solace to parents of his friends who knew he would do a good job his dad said.
There was laughter in the church as Mr Miller asked that people remember Lorcan's stupid hats, his giraffe onesie, his love of everything Harry Potter and his pouting selfies.
The third year medical student was a member of the executive committee of the student medical journal.
He was also elected as club secretary in the UCD hockey club.
His dad recalled how he lived for sport particularly tennis and hockey.
Lorcan was a devoted brother to his younger siblings, Jamie, Poppy and Lucy.
On June 7 he penned a postcard to them from his U.S. workplace, Bubba Gumps.
It arrived on Tuesday.
His heartbroken dad shared it with those in the church.
"As part of my job I have to talk with customers and I always tell them about my amazing brother and sisters and how much I miss them," the post card read.
Lorcan signed off the card with 12 kisses.
Lorcan is also survived by his three younger siblings; his brother Jamie and his little sisters Poppy and Lucy.
Canon David Moynan is leading service at the Rathmichael Parish Church in Shankhill, and the Archbishop of Dublin Dr Michael Jackson is also in attendance.
Members of the UCD hockey team stood in a guard of honour as the hearse arrived at the church.
Tanaiste Joan Burton and the U.S. Ambassador Kevin O'Malley are among the dignitaries in the church today.
Local TD Mary Mitchell O'Connor has also joined mourners.
During the service friends of the popular student are providing the music, and songs from Coldplay and Adele are also being played.
Canon Moynan will pay tribute to Lorcan's many academic achievements during the ceremony.
As a teen Lorcan attended St Andrew's College in Booterstown. During his Leaving Cert year he was elected student officer.
