Romances go sour, but this one really bombed.

A man is going to spend five years in federal prison for using a drone to drop explosives near his ex’s home in eastern Pennsylvania.

Jason Muzzicato, 45, came to the attention of federal prosecutors last year during an investigation of a series of small blasts that had rattled the community of Bangor.

In a search of Muzzicato’s home, investigators discovered a cache of guns and ammunition. The arsenal was a no-no because his ex had a protection from abuse order against him, the CBS affiliate in Philadelphia reported.

Muzzicato denied flying the drone but still pleaded guilty in December to two weapons possession counts and a count of flying an unregistered aircraft.
