Walters' source, company director Thomas C. Davis employing a prepaid cell phone and sometimes the code words "Dallas Cowboys" for Dean Foods, helped him from 2008 to 2014 realize profits and avoid losses in the stock, the Federal jury found. In the trial, investor Carl C. Icahn was mentioned in relation to Walters' trading but was not charged with wrongdoing. Golfer Phil Mickelson "was also mentioned during the trial as someone who had traded in Dean Foods shares and once owed nearly $2 million in gambling debts to" Walter.
