A Florida man convicted of setting off a pipe bomb in his backyard has been sentenced to a year in prison. Court records show that 61-year-old Joseph Caltagirone was sentenced Friday in Tampa federal court. Tampa police say the bomb squad happened to be conducting training last April when they heard a loud explosion. They followed a greyish-white smoke plume to Caltagirone's home, where they found PVC piping, hobby fuse, and chemicals commonly used to make explosives. Investigators also reported finding a pipe bomb that contained an explosive mixture of Tannerite.
