A female sailor was found dead in her room at Fort Myer's military base, NBCWashington.com has reported.
A senior defense official told NBCWashington.com that foul play was definitely involved, and confirmed that the sailor worked at the Pentagon.
The military base reportedly only has a handful of women living in the barracks.
Fort Myers said in a statement that an investigation is under way after the sailor did not appear to work last night.
"As this investigation is beginning and details are just emerging, it would be inappropriate to offer additional comments at this time," the statement said.
