(WBNG) — Federal transportation officials are working to find out what caused one of the deadliest vehicle crashes in United States history.
The National Transportation Safety Board on Monday released a preliminary report into the stretch limousine crash in Schoharie, New York that killed 20 people.
According to the report, the limo, which carried 18 people including the driver, was traveling south on New York State Route 30 on October 6 when it did not stop at the stop sign located at the intersection with New York State Route 30-A.
The limousine, operated by Prestige Limousine, was traveling from Amsterdam, New York to Cooperstown as part of a private party.
A witness at the scene told investigators the limo, operated by Prestige Limousine, traveled through the intersection at a high rate of speed.
Investigators continued saying the limo went into the parking lot of a restaurant hitting an SUV. The collision with the SUV caused the SUV to strike three people walking toward the parked vehicle, investigators add.
Twenty people died in the crash, including the limo driver, the 17 passengers, and two of the pedestrians in the restaurant’s parking lot.
The NTSB determined the limousine is a 2001 Ford Excursion which had been modified to increase the seating capacity.
The report also notes the increased capacity required the limo to be regulated by the New York State Department of Transportation.
“The National Transportation Safety Board (NTSB) continues to gather information on the modifications and mechanical condition of the vehicle, the seat belt usage and survivability of the passengers, and the oversight of the passenger-carrying operation by the New York State Department of Transportation and New York State Department of Motor Vehicles,” the report states.
The crash remains under investigation by the NTSB.
Days after the crash, Prestige Limousine operator Nauman Hussain was charged with criminally negligent homicide. He has also been served with a lawsuit from the family of one of the victims.
