ARLINGTON, Va. — Three Marines who were taken to a hospital after a suspicious piece of mail was opened at a northern Virginia military base have been released.
Leah Rubalcaba, a spokeswoman for Joint Base Myer-Henderson Hall, said in a news release that the Marines were released around 10 p.m. Tuesday. Eight other military personnel members said they began to feel ill but were not hospitalized.
Rubalcaba says people on the Marine Corps side of the base began feeling poorly and complaining of sore throats as soon as the mail was opened Tuesday afternoon.
The Naval Criminal Investigative Service and FBI are conducting a joint investigation.
The base is across the Potomac River from Washington, D.C., bordering Arlington National Cemetery.
