THE heartbroken father of Dublin schoolgirl Lynsey O’Brien who fell to her death from a cruise ship has died tragically.
Mr O’Brien (49) was found dead at his business premises in Ballymount on Sunday.
An autopsy is expected to confirm the cause of death – but sources close to the family say it is not suspicious.
The grieving father was left devastated after his 15-year-old daughter fell to her death from a cruise ship during a family holiday in 2006.
Mr O'Brien, who fought tirelessly for better safety on cruise ships, had released a book detailing his pain at the loss of his daughter.
The O'Brien family - including Lynsey's mum Sandra and her two sisters and younger brother - had left Ireland on December 27, 2005 for a holiday that would take in the Porto Vino Hotel in the grounds of Universal Studios in Orlando, Florida, followed by a cruise leaving from Fort Lauderdale and sailing to the Caribbean.
Lynsey fell overboard from the cruise ship just moments after her dad had put her to bed in her cabin.
A desperate rescue effort by staff on board the ship failed to find Lynsey and her body was never recovered.
Receipts obtained after Lynsey's death show she had been served at least 10 alcoholic drinks on-board, despite being underage.
In a previous interview, Mr O’Brien outlined the impact Lynsey’s death had on the family.
"When Lynsey fell off that ship we all fell off that ship, my life also fell apart," he said after writing a memoir.
Funeral arrangements are expected to be finalised in the coming days.
