A midshipman was found dead in an Annapolis creek Sunday after what was apparently a single-vehicle automobile accident on campus, U.S. Naval Academy officials said.

It is too early to know what caused the accident or when it occurred, said Commander John Schofield, a spokesman for the academy. The Naval Criminal Investigative Service is leading an investigation.

“We are treating this as a single-car motor vehicle accident,” Schofield said. “Our focus is to provide NCIS the support that they need in order to conduct the investigation and help the family and us get some answers.”

The academy notified the young man’s family on Monday but, following Department of Defense policy, will not release his name or other identifying details for another 24 hours.

The accident occurred behind the academy’s Nimitz Library, where McNair Drive winds along College Creek, a tributary of the Severn River. A passerby reported Sunday afternoon that one of the concrete bollards along the creek was missing.

Officials found a white SUV in the water and divers from the Anne Arundel County Fire Department then discovered the victim’s body underwater near a seawall.

The vehicle was recovered from the water Monday morning and is being examined by NCIS and Naval Activity Annapolis Police as part of their investigation.

Schofield said the academy is offering counseling services to faculty and students. “The Naval Academy family is obviously heartbroken,” he said.
