New York State Police have arrested the son of the owner of Prestige Limousine Chauffeur Service, the company involved in the crash that left 20 people dead about 40 miles outside Albany last weekend. Nauman Hussain, whom police described as the company's "operator," was charged Wednesday with criminally negligent homicide for his role in the fatal incident.

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.
