What do you get when you cross a bank robber, a bomb maker and a hoarder? You get George Jakubec (left), a 54-year-old Serbic emigre recently arrested for possessing the single largest hoard of homemade explosives ever found in the United States. Investigators searched his rental home, in the sleepy southern California town of Escondido, and found a startling stash of pentaerythritol tentanitrate (PETN), an explosive used by Al Qaeda terrorists. Federal authorities implemented full body scans at airports to find PETN. A prime ingredient in U.S. military ordinance, PETN was used by the unsuccessful shoe bomber Richard Reid.
