GERMANTOWN, Tenn. (AP) - Germantown Police are investigating the discovery of two plastic pipes that contained dynamite. The Commercial Appeal reported a woman going through her deceased husband's van discovered the devices Monday evening and called police. When officers saw the two pieces of PVC pipe under the driver's seat, they called in the Shelby County bomb squad. Germantown Deputy Police Chief Rodney Bright said about a dozen condos were evacuated as a precaution. Technicians used robots to remove the devices and they were taken away. Residents were allowed to go back home by 11:30 p.m. The pipes were later found to contain dynamite. The newspaper reported the van had belonged to a man who barricaded himself in his condo and committed suicide on July 24.
