NEW YORK AP – A Montana private investigator pleaded guilty to wire fraud Tuesday for bilking a dozen U.S. law offices, including a firm once used by Martha Stewart and former AIG chairman Maurice R. Greenberg.

Michael Lair, 46, admitted in U.S. District Court that he wrongfully accepted at least $200,000 from the firms between 2003 and 2006 by promising to deliver information about highly publicized lawsuits, including one involving Greenberg.
