UTAH ATTORNEY GENERAL'S OFFICE
Inventor Imposter Jailed.
A man who claimed to have invented a Dick Tracy wrist watch communicator was sentenced to jail for defrauding investors. The judge ordered David Yurth to serve a year behind bars unless he could come up with a plan to pay victims more than $150,000. Asst. Attorney General Richard Hamp prosecuted the case.
Whom is David Yurth defrauding now?
