Tributes for Perth native title lawyer Dan O'Dea who died after City to Surf Jeffrey Ong, 32, a dentist who collapsed and died at the end of the 12km City to Surf on Sunday. Perth native title lawyer Daniel O'Dea, who died from heart complications days after the City to Surf. A PERTH lawyer has died from a suspected heart attack just days after competing in the City to Surf - the second death related to the charity run. Daniel O'Dea, a member of the National Native Title Tribunal, collapsed soon after completing the charity event on Sunday. Mr O'Dea, aged in his early 50s, died in his sleep on Tuesday night after he was discharged from Sir Charles Gairdner Hospital following heart surgery. It's understood he underwent surgery at SCGH to clear a blockage in his heart and was sent home in a stable condition. His death is the second linked to this year's City to Surf, which attracts thousands of runners. National Native Title Tribunal president Raelene Webb said Mr O'Dea would be ``deeply missed" by those who knew him. ``Dan's passing is a great loss to the tribunal and to Australia's native title system, but he leaves a valuable and enduring legacy - not least his commitment, deep experience and good humour," she said. ``On behalf of the members and staff of the tribunal, we extend to Dan's family and to his many friends, our sincere condolences. Between 1996 and 2002, he achieved many native title outcomes for Aboriginal people in the Western and Central Desert regions. Dentist Jeff Ong, 32, died in hospital after he too suffered a suspected heart attack just moments after crossing the 12km finish line.
