The agency said there was no surveillance video footage that provided concrete leads to identify who may have left the baggie in the White House’s guest lobby.
The Secret Service said on Thursday that it had closed its investigation into how cocaine ended up in the guest lobby of the West Wing after security video failed to provide any leads and no fingerprints were found on the baggie.
Earlier this month, the small plastic envelope was found in an area of the West Wing that visitors and staff members often pass through during the day. When staff members want to bring relatives or friends on tours of the West Wing, they usually do so at night and on the weekends.
“Without physical evidence, the investigation will not be able to single out a person of interest from the hundreds of individuals who passed through the vestibule where the cocaine was discovered,” the Secret Service said in a statement issued on Thursday.
