The private detective sub-contracted in the so-called HP Spy Scandal to secure telephone records of journalists, HP board members and HP employees, pleaded guilty to federal charges in San Jose on Friday, opening the way for him to testify against other co-accused. 

Bryan Wagner, a self-confessed "little guy" in the scandal, offered to testifly against others in exchange for leniency. If he was found guilty of the federal charges without plea bargaining, Wagner could have faced a minimum two-year sentence.
California state charges have been laid against Wagner and four others, including former HP chairman Patricia Dunn and former ethics director, Kevin Hunsacker.
Wagner was the first to face federal charges in the scandal.
