A spokesman from the California attorney general\u2019s office Friday said that Attorney General Bill Lockyer at this point does not have any evidence to charge Hewlett-Packard (HP) Chief Executive Officer and President Mark Hurd with a criminal offense in the ongoing investigation into HP\u2019s probe of journalists and board members.However, Thomas Dressler, a Lockyer spokesman, said that Lockyer and his office are still in the middle of an investigation, so it does not mean Hurd is in the clear yet."The key words are \u2019at this point,\u2019" he said Friday. "We\u2019re not ruling anyone out in terms of criminal culpability. We have much more work to do, many more documents to review, more people to interview."The probe could have serious consequences for HP as evidence continues to surface that investigators not only used pretexting -- or obtaining phone records under false pretenses -- but also physical surveillance and e-mail tracking software that was placed on at least one target\u2019s computer without her knowledge to gather information. HP has acknowledged that it undertook an investigation of employees, board members and journalists, in an attempt to find out who on the HP board was leaking information.A report in The Washington Post Thursday cited e-mail that indicated Hurd knew about details of the investigation, and HP\u2019s share price began falling after reports that suggested he approved elaborate spying tactics to obtain reporter information.Patricia Dunn, HP\u2019s chairman, already has agreed to step aside as chairman in January in the wake of the scandal, and two others also have resigned from the board. Hurd will take over as chairman of the board when Dunn leaves, though she will remain on the board.Hurd is expected to speak publicly for the first time about the scandal in a press conference at 4:05 p.m. Eastern Standard Time. According to HP spokeswoman Emma Wischhusen, Hurd will not field reporter questions, but will make only prepared comments. A representative from a law firm representing HP, Morgan, Lewis & Bockius, also will speak at the press conference.-Elizabeth Montalbano, IDG News Service (New York Bureau)Keep checking in at our HP Spying Scandal page for more CIO.com coverage of this unfolding story.Keep checking in at our CSO Security Feed page for updated news coverage.
