A man is in critical condition after being rescued from a submerged car at the Columbia Island Marina. Rescue personnel from Arlington, D.C. and Reagan National Airport were dispatched to the marina at 9 a.m. for a report of a vehicle in the water. Within minutes they rescued the man through the car window, treated him on the scene and rushed him to George Washington University Hospital, said an Arlington fire department spokeswoman. The submerged vehicle was located near the marina’s boat ramp. There’s no word yet how it ended up in the water. Divers searched but did not find any other victims. They were aided in the search by the D.C. fire boat and the U.S. Park Police Eagle 1 helicopter.
