Bomb Maker Turned In By Mom Gets Prison Time

A Warrington man turned in by his mother on suspicion of making pipe bombs will spend two and a half years in prison.

John Grzyminski, 50, of Saddle Drive, was sentenced in federal district court in Philadelphia on Friday to 30 months in prison followed by three years of supervised release, according to the U.S. Attorney's Office.

Grzyminski pleaded guilty in September to illegally possessing three pipe bombs, which his mother, Catherine Wilson, discovered in the house they shared in the 1800 block of Saddle Drive.

On May 9, Wilson called Warrington Township police to report that she felt threatened by her son. 

The police left, but returned to the home when Wilson called back to say she had found what she believed was a pipe bomb on the kitchen counter.

The Philadelphia Police Department Bomb Disposal Unit and federal agents from the Bureau of Alcohol, Tobacco, Firearms, and Explosives also were called to the home.

Bomb technicians found two more bombs in an upstairs bedroom and bomb-making materials in the garage, authorities said. Grzyminski's whereabouts, however, were unknown.

Solebury Township police found him the next day, identifying Grzyminski during a traffic stop on May 10. He was arrested and charged with illegal possession of an unregistered explosive device.

"He told police that he had made the bombs for hunting bears, and that he also liked to throw them into lakes for entertainment," prosecutors said in a statement.
