The funeral takes place in Arklow this morning of James Sheehan, whose body was found in the Avoca River last week.
Hundreds of volunteers joined in the search for the 18-year-old when he disappeared after a night in a club with his friends on Saturday, August 18.
His body was eventually found last Thursday by a volunteer diver.
The mass takes place at St. Mary and Peter Church, Arklow at 10am.
