(CNN) We learned this past weekend about the existence of a surveillance video in the Michael Brown case that was previously undisclosed to the public. Michael Brown died on the afternoon of August 9, 2014 after being shot multiple times by Ferguson, Missouri, Police Officer Darren Wilson . In this video , Michael Brown looks to be in the same convenience store that he would later be accused of robbing some ten hours later -- seemingly engaged in a transaction with store personnel. Pollock asserts that the footage establishes that Brown was trading marijuana for a bag of cigars -- which Brown apparently left in the store, intending to pick up later. If Pollock's theory is correct, Brown would not have been robbing the store later that day, which was the police's explanation.
