Former Miami Dolphins quarterback Dan Marino is among a group of prominent investors accusing Wachovia Mortgage Corp. of fumbling a South Florida real estate deal and costing them about $43.97 million in the process.

Marino, billionaire Wayne Huizenga and former AutoNation Inc. executive Michael Maroone invested in two plaintiff companies facing off with the defunct bank in a trial underway in Fort Lauderdale before Broward Circuit Judge John B. Bowman. They accuse the bank of violating the Uniform Trade Secrets Act by inadvertently disclosing contact information for would-be buyers through an email blast, leading to a class action lawsuit and the cancellation of 119 sale contracts.
