The stretch limousine involved in a deadly crash in upstate New York on Saturday had recently failed a state safety inspection and its driver did not have the proper license to drive the vehicle, Gov. Andrew Cuomo said Monday.

The crash killed all 18 occupants of the modified limo and two pedestrians. Federal officials said it is the deadliest transportation accident in the U.S. since a 2009 plane crash.
