SEATTLE , Washington -LRB- CNN -RRB- -- A 16-year-old girl was found dead and another girl was found unconscious in an Army barracks at Fort Lewis near Tacoma , Washington , during the weekend , a base spokesman said Monday . `` Neither of the two women had any outward signs of trauma on them , '' said Fort Lewis spokesman Joseph Piek . He said that an Army solider who was `` allegedly an acquaintance '' of the two 16-year-olds was questioned by investigators , but no arrests had been made . The spokesman said the name and rank of the soldier who had been questioned was not being released . According to an Army news release , the names of the two girls `` are not being released due to their ages , their civilian status , and the nature of the ongoing investigation . '' The Fort Lewis Criminal Investigation Division is trying to determine why the two girls were in the barracks , where soldiers live , and what led to their conditions when they were found . Emergency personnel from the base responded to a 911 call about 3:30 a.m. Sunday and found the two girls in one of the barracks . A doctor declared one of the girls dead on the scene , and the second girl was transported to Madigan Army Hospital , where she was in stable condition Monday . The Office of the Armed Forces Medical Examiner is conducting an autopsy , Piek said , and it will be at least a week before results are complete . Both girls are from the nearby South Puget Sound area but were not related to anyone living on base , Piek said . Both girls ' families had been notified , he said . Although Fort Lewis is not open to civilians , they can be escorted in by a soldier living there if they have identification and a reason for coming onto the facility . The circumstances of how the girls came unto the base are under investigation , Piek said , but there was no evidence that security had been compromised . About 30,000 military personnel are based at Fort Lewis . Barracks where soldiers live are usually split into rooms for one to three soldiers , Piek said . Details about the barracks where the girls where found were not released .
