The FBI is investigating a bizarre case involving two men dressed as women who drove a stolen vehicle onto the National Security Agency campus in Fort Meade, Maryland on Monday morning.

Officials believe that the driver may have mistakenly driven to the NSA headquarters after getting off at a restricted exit on the Baltimore-Washington Parkway. That's when NSA officials say that the driver ignored police commands to stop and instead drove toward a police car an officer opened fire. Eventually, the stolen SUV crashed into the cruiser.

"The driver failed to obey an NSA Police officer's routine instructions for safely exiting the secure campus. The vehicle failed to stop and barriers were deployed," said Jonathan Freed, NSA director of strategic communications, in a statement, reports CNN.

As a result, a man identified as Ricky Shawatza Hall died at the scene, while the other man was taken to a hospital for treatment. An NSA officer was also injured and hospitalized following the incident.

A federal law enforcement official announced that investigators are looking into whether the men were under the influence of drugs following a night of partying. Authorities also say that cocaine was found in the vehicle.

A third man says that he spent the night with the two men in a hotel in Howard County, not far away from NSA Headquarters. However, he said he awoke Monday morning to find that the men had stolen his Ford Escape, which is the same vehicle involved in the incident.

"We are working with the U.S. Attorney's Office in Maryland to determine if federal charges are warranted," the FBI said in a statement.

A spokeswoman for the Baltimore office of the FBI also confirmed that authorities "do not believe [the incident] is related to terrorism," while a law enforcement official added that "This was not a deliberate attempt to breach the security of NSA. This was not a planned attack," reports The Washington Post.
