The FBI has closed its investigation into the deadly shooting at an entrance to the National Security Agency in March, officials said, and federal prosecutors have declined to bring charges against anyone involved.

Investigators said two men drove a stolen SUV up to a gate of the agency at Fort Meade and ignored orders to turn around. NSA police opened fire, killing the driver and wounding the passenger.


The FBI identifed the driver as Ricky Hall, 27; friends said Hall identified as a transsexual woman known as Mya.

The passenger, whom authorities have not identified, was treated for gunshot wounds at a local hospital. The person's condition was not clear Tuesday.

U.S. Attorney Rod J. Rosenstein, the chief federal prosecutor for Maryland, said video evidence showed that Hall ignored the commands of NSA police and was "racing toward the officer who fired at the vehicle."

"There was no crime committed by the officers," Rosenstein said. He said there was no basis for filing federal charges against the passenger.

While the incident raised concerns of a terror attack, FBI officials quickly ruled out terrorism and indicated that the pair might have ended up on the base by mistake.

Police said they had traveled from Baltimore to a motel in Elkridge with a 60-year-old man in the hours before the shooting. The older man told authorities that the pair stole his SUV and left the motel.

Howard County police said Tuesday they had closed their investigation and would not bring charges.

NSA police said Hall ignored commands to turn back and instead accelerated toward a police vehicle, at which point an officer opened fire.

Aerial images showed two damaged vehicles at the entrance and bits of wreckage strewn across an access road.

The pair were not the first people to make a wrong turn off the Baltimore-Washington Parkway and end up at the gates of the agency. But while other incidents have frustrated motorists, they did not turn deadly.
