John Grzyminski's life just went from bad to worse.

The 50-year-old man has been charged federally with knowingly possessing unauthorized destructive devices, just a few days after cops found three pipe bombs inside his Warrington home.

It's unclear yet if he'll appear in U.S. Magistrate Court later today.

According to a criminal complaint that was filed Thursday in the Eastern District of Pennsylvania, Grzyminski allegedly argued with his mother, Catherine Wilson, and his brother, Michael, when Wilson returned home Wednesday from a hospital stay for surgery.

Grzyminski had removed his mother's wheelchair access to their house, on Saddle Drive near Carriage Way. He fled following the argument, but Wilson called 9-1-1 and told police that she was afraid because her son had numerous guns in the house, according to the complaint.

Cops told Wilson that her son was allowed to have the legally-owned firearms because he had no criminal history.

Wilson later found a pipe bomb,with a fuse attached, in the kitchen. Police soon swarmed the quiet neighborhood, and found two other pipe bombs in a bedroom.

Grzyminski returned to his house, and told police that the pipe bombs were actually fireworks for the Fourth of July, according to the complaint. He left the scene, but was apprehended Thursday by cops in Solebury Township, Bucks County, and charged locally with recklessly endangering another person, risking a catastrophe and related offenses.

An agent from the Bureau of Alcohol, Tobacco, Firearms and Explosives noted in the complaint that fireworks are usually housed in paper tubing; the bombs in Grzyminski's house were house in PVC pipe, "which would shatter and send high velocity shrapnel in every direction upon explosion."
