THE father of tragic Lynsey O'Brien, who fell to her death from a cruise ship, has died suddenly.
Paul O'Brien (42) was found dead, reportedly at his business premises in Ballymount.
It is understood that he contacted a family member over the weekend who alerted the emergency services.
The father-of-four had been struggling to cope with the trauma of losing Lynsey (15) on a dream holiday trip onboard a cruise.
Schoolgirl Lynsey fell overboard into the Caribbean Sea from a Carnival Cruise Liner on January 4, 2006.
It was discovered that Lynsey had drunk a number of vodka cocktails in two hours in one of the Costa Magica cruise ship's bars, despite being underage.
Her sister Imelda witnessed the fall from the ship's upper decks at about 2am.
Although she tried desperately to open the balcony door to help her sister, as she appeared to cling to the ship's railings, by the time she got out, Lynsey had fallen 140ft into the sea.
The Dublin businessman recently spoke openly about his pain of losing his beautiful daughter and it was revealed that he had attempted to take his own life 10 times.
The self-made millionaire, who branched into property, reportedly fell on hard times and suffered with bipolar disorder.
"By the time I was 30, I had a million in the bank," he said recently.
"Now I'm completely broke. The banks have moved in. I'm going to be homeless soon."
