Dean Foods Co's former chairman Thomas Davis said he threw his cellphone into a Dallas creek to hide his role in an insider-trading scheme after FBI agents visited his home, according to a transcript of his guilty plea. In a secret hearing in Manhattan on Monday, Davis told a federal judge about his efforts to hinder the investigation into the scheme as FBI agents and regulators closed in on him. U.S. authorities on Thursday unveiled charges against Davis and gambler William "Billy" Walters for running the insider trading scheme that netted over $40 million and included a tip that benefited professional golfer Phil Mickelson.
