US Tax Cheats Picked Off After Adviser Mails It In

Everybody knows the danger of sending things inadvertently in an e-mail. Beda Singenberger's case shows you also have to be pretty careful when you mail things the old-fashioned way.

Over an 11-year period, federal prosecutors charge, Swiss financial adviser Singenberger helped 60 people in the U.S. hide $184 million in secret offshore accounts bearing colorful names like Real Cool Investments Ltd. and Wanderlust Foundation.

Then, according to a prosecutor, Singenberger inadvertently mailed a list of his U.S. clients, including their names and incriminating details, which somehow wound up in the hands of federal authorities.

Whoops!
