US terror case hearing reveals details on work by Muslim convert informant

NEW HAVEN, Connecticut: William Chrisman had three wives and nine children to support and struggled with panic attacks, but the Muslim convert was determined to help the United States after the Sept. 11, 2001, terrorist attacks. He became an informant for the FBI and ended up in contact with two other Muslim converts suspected of supporting terrorism. His work helped authorities charge both men. Derrick Shareef, 23, pleaded guilty to plotting to set off grenades in an Illinois shopping mall. Hassan Abu-Jihaad, a former U.S. Navy sailor, has pleaded not guilty to charges he gave terrorists secret information about the location of Navy ships and ways to attack them.
