From U.S. Army Test and Evaluation Command:
ABERDEEN PROVING GROUND, Md. (June 11, 2013) A carbon dioxide tank exploded outside a building owned by the Aberdeen Test Center, U.S. Army Test and Evaluation Command, Monday at approximately 10 p.m. causing a loud boom to be heard across Aberdeen. No one was injured.
The building located adjacent to the tank sustained substantial structural damage. The building is used for sampling and analysis in support of testing military systems. Two other buildings, nearly a half mile away, also sustained damage from the blast.
Access and entry to the building is prohibited at this time. The incident remains under investigation by special agents from the U.S. Army Criminal Investigation Command, local APG authorities, and the Aberdeen Test Center.
“Although criminal activity is not suspected at this point in the investigation, we have not completely ruled it out in order to conduct a complete and thorough investigation,” said Jeffrey Castro, the spokesperson for Army CID.
