NIAGARA FALLS, N.Y. (NEWSnet/AP) — Federal Bureau of Investigation has ended its investigation of a car crash that killed two people at a border checkpoint in Niagara Falls.

FBI found no evidence that it was a terror attack.

The announcement came several hours after the vehicle raced through an intersection, hit a median and was launched into the air before slamming into a line of booths and exploding at Rainbow Bridge in Niagara Falls.

Local police are handling the case as a traffic investigation.

"A search of the scene revealed no explosive materials, and no terrorism nexus was identified,” the FBI's Buffalo office said.

Investigation  Niagara Falls Police Department’s Crash Management Unit has taken control of the investigation, according to  the city's police department. Due to complexity of the incident, investigation “will take some time to complete,” the department said.

The two people who died were a husband and wife, according to a person briefed on the investigation who spoke to The Associated Press on condition of anonymity. Identities have not been released.
