The Coast Guard said the parents of 23-year-old Falcon A. Riley sent an email on Thursday reporting that their son had last been seen at Cape May on Aug. 25. The Coast Guard did not know his hometown.
Riley was believed to be aboard a green-and-white 30-foot Hunter sailboat, the "Reverie."
No further details were available. The Coast Guard said it was attempting to get more information about Riley and the boat's itinerary from the parents.
