But Manchester United never authorized using the park as a U.S. training ground, said Andrew Ward, a spokesman for the team. Ward said the purported letter from the UK-based club that was included in the prospectus is fake. 

Officials with at least six other organizations that were said to have “pre-contracts” told Bloomberg News that they never signed such agreements, with two of them disputing the veracity of letters expressing interest in the facility.

Among them was Real Salt Lake-AZ, a youth soccer league affiliated with Major League Soccer’s Real Salt Lake. The prospectus included a letter from Real Salt Lake-AZ’s executive director, Brent Erwin, saying the club agreed to relocate its 7,000 players, tournaments and camps to Legacy’s park.

But Erwin said the organization made no such commitment and the signature on the letter isn’t his. 

“We never signed or committed anything to Legacy Sports Complex,” Erwin said in an email. “We took the meeting when they were pitching the complex but made the decision to move no games, training or tournaments to the facility.”

Miller didn’t respond to a list of questions about the statements in the offering documents, which was sent to his email accounts, his LinkedIn profile, and to a spokeswoman for his company. 

Michael Grimm, a spokesman for B.C. Ziegler & Co., the investment bank that underwrote the bond issues, declined to comment for this story. The underwriter was among those sued in the Saybrook-led lawsuit, and Grimm said the firm would address any questions about its role “in the context of any litigation.”

Miller had struggled in business well before the Legacy project. 

In 2005, he purchased a small pool-cleaning company from John Hunt, who later sued Miller for allegedly failing to pay for the business. Miller agreed to settle and the court entered a judgment against him after he failed to pay it, according to court records. Five years later, after trying to raise money to get the sports park project off the ground, Miller was ordered to pay $96,000 to Monica Labadie, who sued him for failing to repay a loan she was told would bankroll the project. 

Unable to pay, he filed for bankruptcy in 2012—after twice doing so in the early 1990s—listing debts of $539,456 and assets of $890. Labadie said she was eventually paid what she was owed but Hunt said he gave up trying to collect.
