John Gilligan's crime gang was destroyed after Veronica Guerin's murder in June 1996, during the massive garda investigation into her death. Gilligan fled the country but was later extradited back to Ireland.
Although he was cleared of Guerin's murder he was convicted on drugs charges.
At the time of his arrest, gardai put his earnings from crime at €17m. However, the money never materialised.
As well as Jessbrook, which was worth around €5m at the height of the boom, CAB also seized around €700,000 from various bank accounts linked to Gilligan.
His wife, Geraldine was also served with tax demands. His council house and two properties in his children's names were also seized.
Darren Gilligan told a court that he came into €15,000 in a personal injury claim, which he gave to his father. His father gambled it and won enough to buy the house in Lucan.
The Gilligan family eventually lost their claim that the properties were bought with legitimate earnings in the High Court in 2011. They were given leave to appeal to the Supreme Court. Gilligan's legal aid bill is believed to have cost the State an estimated €4m.
During the lengthy court proceedings, Gilligan claimed at various times that he made his fortune as a professional gambler, and also by acting as a currency changer in the UK and the Netherlands.
During one hearing he prepared four ringbinder folders full of betting dockets.
In 2008, Geraldine Gilligan, who is separated from her husband, claimed that she lived on €80 a week from renting out grazing land on Jessbrook.
She survived on an income of €5,000 a year from a local stud farm owner, who rented grazing rights from her.
She also took in €800 a month from the former family home in Corduff, Blanchardstown.
Otherwise, she sometimes helped out when she visited her daughter, Tracey, who ran a bar called The Judge's Chamber in Alicante, Spain. But, she said, she didn't share in the proceeds of the bar.
