Around 11:30 this morning, staff members found a suspicious envelope in the mailroom at Fletcher Johnson Education Center inside H.D. Woodson High School, located at 4650 Benning Road SE. A D.C. Fire and EMS special operations team responded to the scene and are investigating, along with other law enforcement officials, including representatives from the FBI. D.C. Fire and EMS spokesperson Pete Piringer says that the letter “may be similar to those that were received last week,” but that “the item has been isolated…and seems to be confined to the administrative mailroom area.” No illnesses or injuries have been reported, and Piringer notes that FEMS expects to turn the investigation over to federal authorities shortly.
