IMGG put out a PR Mar 24 2011 announcing a managment stock buyback in the year period from Mar2011 until Mar2012
During that period Chris Sohn sold 3 million shares
Dean Janes had 38 million of his shares go missing (though 15 million of them went to collateralize a personal loan and it appears the lender has taken posession and/or sold those shares)
that stock buyback PR came while the stock price was in freefall and came 1 week before Cranshire was allowed to begin selling their shares
To me, that would appear to be within the 4 corners of the definition of Fraud.
