PHILADELPHIA - John Grzyminski, 50, of Warrington, PA, was sentenced today to 30 months in prison for the illegal possession of an unregistered explosive device. On May 9, 2012, the defendant’s mother called the Warrington Township Police Department to report that she felt threatened by the defendant. Police arrived and, after the officers left, the defendant’s mother found a pipe bomb on her kitchen counter. The Warrington Police Department was again dispatched to the residence along with the Philadelphia Police Department Bomb Disposal Unit (PPDBDU) and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.

Bomb technicians found two additional pipe bombs in an upstairs bedroom and bomb making materials in the garage. Grzyminski was arrested after being stopped by the Solebury Township Police on May 10, 2012. He told police that he had made the bombs for hunting bears, and that he also liked to throw them into lakes for entertainment. The defendant stated that he had manufactured the bombs over a 12 year period. He pleaded guilty to the charge on September 17, 2012.

In addition to the prison term, U.S. District Court Judge Stewart Dalzell ordered three years of supervised release.

The case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives and is being prosecuted by Assistant United States Attorney Judy G. Smith.
