State officials have released more information on a California man who raised terrorist concerns after threatening to kill two Iowa state troopers and a police officer during traffic stop earlier this month. It started as a routine traffic stop near mile marker 16 on Interstate 80, but became much more. State Police initially pulled over 44-year old Michael Wagner of San Diego for not wearing a seat belt. Police recorded their conversation with Wagner where he allegedly made several threats. A semiautomatic handgun, three bulletproof vests, and more than 500 rounds of ammunition were found during a search of the car. He has pleaded not guilty to those charges. But court documents obtained by The Associated Press say Wagner claimed to have knowledge of Al-Qaida and Taliban terrorist activities in the San Diego area. He went on to say he knew people and groups associated to Al-Qaida and the Taliban. The state police search also turned up flight-training manuals, Arabic documents, and night-vision goggles.
