An off-duty Bladensburg (Md.) Police officer fatally shot himself before crashing into another vehicle on Saturday in Anne Arundel County.

Officer Brian Johnson, a nine-year veteran, was driving his police cruiser east on Route 100 at 9 a.m., when he crossed the median and struck a vehicle heading west, according to an Anne Arundel County release.

The county medical examiner ruled the death a suicide Monday morning, after finding a gunshot wound to Officer Johnson's upper body. Officials previously said the officer suffered a medical emergency before the crash.

Officer Johnson suffered significant injuries in the crash and was transported to Baltimore Washington Medical Center, where he was pronounced dead. The operator of the other vehicle was treated and released at the scene.
