The U.S. Secret Service has closed its probe into cocaine discovered at the White House without identifying a suspect.
The agency said Thursday that it had conducted a “methodical review,” including identifying several hundred people who may have accessed the area of the White House where the cocaine was found, but was unable to obtain physical evidence to link the substance to anyone.
The agency was also unable to find surveillance video footage to help investigators identify who brought the illicit drug into the complex.
