FILE - In this April 25, 2007 file photo, law enforcement authorities, including U.S. postal inspectors, search for evidence at the home of John P. Tomkins in Dubuque, Iowa. Tomkins was arrested and charged with sending dud pipe bombs and threatening letters to investment companies in Denver and Kansas City in an effort to drive up stock prices. On Thursday, May 3, 2012, at federal court in Chicago, Tomkins will deliver his own closing at his trial. Before closing arguments, Tomkins could also call himself to take the stand. The 47-year-old represents himself and speaks about himself in the third person. (AP Photo/Charlie Neibergall, File) less
