The mystery of who carried a bag of cocaine into the White House appears to reportedly still be unsolved.
According to three Secret Service officials involved with the inquiry, the Secret Service investigation has come to a conclusion without producing any useful forensic or video evidence identifying the perpetrator.
The little plastic baggie containing the powdered material was investigated at two government laboratories and subjected to sophisticated testing after it was discovered in a storage cubby at the White House on a Sunday night earlier this month.
However, no useable fingerprints or DNA were recovered, according to the authorities.
On July 2, a Secret Service agent in uniform noticed a little plastic baggie in a storage cubby at the West Executive Avenue door on the ground floor.
This unexpected security lapse was discovered.
Staff members, independent contractors, military personnel, and some guests can leave personal goods and electronic devices that are not allowed in some sections of the West Wing in the storage cubbies.
The Situation Room, which is undergoing repairs and is temporarily out of commission, is next to the foyer; while construction, secret briefings are being held in a different secure conference room.
Without that type of tangible proof, the inquiry is at a dead end.
Following questions from legislators on the investigation and security procedures at the White House, Secret Service representatives are providing updates to members of the House Oversight and Homeland Security committees on Capitol Hill on Thursday.
