The names of hundreds of Americans have surfaced in the Panama Papers, including a handful of U.S. businessmen accused or convicted by U.S. authorities for ties to financial crimes or Ponzi schemes. The identities of the Americans emerged from the treasure trove of documents obtained by the German newspaper Süddeutsche Zeitung , the U.S.-based International Consortium of Investigative Journalists and hundreds of other media organizations.

The consortium has so far identified more than 200 people with U.S. addresses who own companies in the leaked data from the Panamanian law firm Mossack Fonseca. Some appear to be retirees purchasing real estate in places like Costa Rica and Panama, according to the consortium. But there are at least a few Americans in the leaked files who have faced charges for serious financial crimes in the U.S.

Here are some of the Americans who have been charged or convicted of financial crimes that have surfaced in the massive data leak, according to the media consortium. Their identities were first reported by McClatchy Newspapers.

Benjamin Wey , a Wall Street financier, was charged in September with securities fraud, wire fraud, conspiracy and money laundering for using family members to help him stealthily amass ownership of larger blocks of stock in companies through so-called “reverse merger” transactions between Chinese companies and U.S. shell companies. In the process, he reaped tens of millions of dollars of illegal profit by manipulating the companies’ stock prices, the indictment charges. Prosecutors say he was aided by his banker in Switzerland, Seref Dogan Erbek, who was also charged in the alleged scheme.
