(NEW YORK) -- A number of unusual signs point to the possibility that missing millionaire Guma Aguiar could be hiding out in the Netherlands, according to his wife's attorney.
Aguiar, 35, was last seen on June 19 in Fort Lauderdale, Fla. Early the next morning, his 31-foot fishing boat, the T.T. Zion, washed up on a Fort Lauderdale beach with the engine running and lights on, but no sign of its Brazilian-born owner.
Since then, Aguiar's mother, Ellen Aguiar, and wife Jamie Aguiar have been embroiled in a nasty legal fight for control of his assets, valued at over $100 million.
Speculation that Guma could still be alive has surrounded this mysterious case ever since his disappearance. The troubled millionaire had a history of legal problems and psychiatric issues.
Attorneys have been eager to interview Guma's associates, friends and family members. Ellen has been deposed and maintains she does not know anything about her son's disappearance, according to attorney William Scherer, but an attempt to interview Guma's sister Angelika Aguiar Drew took a baffling turn.
In response to a subpoena to appear in court for a deposition, Guma's sister sent the court an affidavit from the Netherlands.
"She sent the Florida court an affidavit signed in the Netherlands that she intends to move her residence or has moved her residence to the Netherlands," Scherer, who represents Jamie, told ABC News.
Guma's sister is married to Corey Drew, whom Scherer calls "one of [Guma's] insiders all along."
"Angelika and Corey have indicated that they want to move or have moved to the Netherlands. They're trying to avoid us, taking this deposition and being subject to Florida court," Scherer said. "So she filed this affidavit and then we are wondering, 'What's the Netherlands?'"
After looking into the Netherlands, Scherer claims he discovered that another one of Guma's "very close business associates" has also relocated to the Netherlands. Scherer declined to give the associate's name, but the information has left him baffled.
"Why are they all going to the Netherlands? What's going on there? We haven't been able to get them under oath to ask them," he said. "This all may be a coincidence, but it may not be."
Police have investigated Guma's disappearance as a missing person case. While some have suggested that the financially and mentally troubled millionaire may have committed suicide, no body has been found. There have also not been any reported sightings of him.
