8 months after a high-speed crash and explosion on Niagara Falls' Rainbow Bridge killed a Grand Island couple, the police investigation has concluded with the crash's cause remaining unknown. The Nov 2023 crash involved a high-powered Bentley luxury car and killed Kurt and Monica Villani, both 53. The probe is considered closed but can be reopened if new evidence emerges. Investigators were hindered by the destruction of the car's event data recorder, or black box, in the incident.
