A former Iowa machinist has been sentenced to prison for mailing two pipe bombs and a dozen threatening letters to investment firms and advisors to help increase the value of the stock he owned in two companies.
John Tomkins, from Dubuque, Iowa, received 37 years in prison for, among other things, using a destructive device while mailing a threatening communication. Evidence presented at trial showed that the mailed parcels contained improvised explosive weapons (“pipe bombs”) which were capable of exploding and causing serious injury or death. Each parcel also contained a letter which stated “BANG!! YOU’RE DEAD.” Some of the letters were signed by “THE BISHOP” and concluded with “TIC TOC.”
