"Although we have not completely ruled it out in order to conduct a complete and thorough investigation, we do not suspect foul play at this point in the investigation," Army Criminal Investigation Command spokesman Chris Grey said in a statement.
Officials positively identified the man and confirmed that he was not an active-duty service member. Further information is being withheld until a next of kin has been notified. The incident was isolated and there is no threat to public safety.
