(Newser) – Police nabbed "The Bishop"—the bandit who's been sending unwired pipe bombs to Midwestern investment firms for the last two years—they announced yesterday. John P. Tomkins, a 42-year-old machinist in DuBuque, Iowa, was charged with one count each of mailing an extortion letter and possessing an unregistered explosive device.

Investigators used handwriting, financial records, and a glimpse of Tompkins's car window, caught in a photo accompanying one of the bombs, to narrow in on their suspect. A search of his home and a nearby storage unit yesterday afternoon turned up multiple packages containing bombs, which were detonated by authorities at the site.
