Keys woman guilty in federal tax case

An Islamorada woman pleaded guilty Tuesday in U.S. District Court for the Eastern District of Michigan to one count of filing a false tax return, the Eastern District U.S. Attorney's Office said.

Justina Black, 53, previously lived in Washington, Mich. Black is also known by the names Justina Kopek, Guistina Kopek and Justina Fazzolari.

The amount of money involved in the tax case wasn't immediately available.

According to court documents, Black operated a company called Justina Inc. which was in the business of buying and selling gold through "gold parties." At these parties, prosecutors say, people sold gold to representatives of Justina Inc., which then sold the gold to another company.

The feds say Black "caused" corporate tax returns to be filed for Justina Inc. that did not report the full amount of gross receipts the company received for the tax years 2009 and 2010. On the 2008 through 2010 corporate tax returns for Justina Inc., Black also falsely claimed deductions relating to a property that was not an asset of the company.

She is set for sentencing on March 31 and faces up to three years in prison.
