Real estate tycoon Steven Posner has died in a high-speed boat crash near Miami that killed another man and left two other men injured, authorities said Tuesday.

The Florida Fish and Wildlife Conservation Commission issued a statement confirming the death of Posner, the 67-year-old son of the late corporate raider Victor Posner, and said it is investigating Monday's crash on Biscayne Bay.

The agency said a friend of Posner's, 60-year-old Clive Warwock, was killed and that the tycoon's 64-year-old cousin, Stuart Posner, was seriously injured. Both men were aboard Posner's boat.

The statement said Posner's 44-foot race boat and a similar 46-foot vessel crashed into each other and that the operator of the second boat, 27-year-old Friedrich Eigelshoven of Fort Lauderdale, suffered minor injuries. A passenger on the second boat was not hurt.

The crash happened about 1 p.m. Monday in clear weather. The Fish and Wildlife Commission said the two boats — each capable of speeds approaching 100 mph — appeared to be racing before colliding, according to witnesses.

Friends and family members said Posner loved fast boats and entertaining guests.

Steven Posner made headlines a decade ago in a battle with his father over trust fund money. The matter was settled in 2001 and netted Posner an estimated $100 million in real estate holdings. The deal was struck after father and son tossed a gold coin before a Miami judge to determine Steven Posner's share.

Victor Posner died in 2002.

Steven Posner's sister Gail died earlier this year of cancer. She left millions of dollars for her two dogs in a will that was challenged by her son.
