Three men who worked at the George Washington University bookstore were found guilty of emptying its shelves rather than stocking them, stealing approximately $200,000 worth of textbooks with the help of a D.C. hot dog vendor.

District residents and bookstore employees Darrell Coleman, 21, and Kiry McCullum, 22, stole books off the shelves, placed them in boxes and passed those off to Falls Church resident Hao Nguyen, 42, a hot dog vendor who sold the stolen merchandise online, according to prosecutors.

The three men executed the plot for more than a month between December 2010 and January 2011, costing the bookstore roughly $200,000.

Nguyen sold some of the books online for more than $50,000, prosecutors said.

The defendants were convicted of conspiracy and several counts of first-degree theft in U.S. District Court. All three men are scheduled to be sentenced on Jan. 18.

A third bookstore employee pleaded guilty to similar charges in August.
