As for the investigation into why this happened, the FBI told News 8 that it’s coming to close and emailed over this statement:

With tomorrow marking one year since the tragic Kodak Center vehicle collision, the FBI sends our deepest condolences to family and friends of the victims. These lives were taken unfairly too soon. Over the past year, the FBI has diligently investigated this case. The FBI recognizes many want to “why” this incident occurred; however, our findings have not changed. We have uncovered no evidence of an ideology and no nexus of terrorism. What happened on January 1, 2024, was a horrible, senseless incident. We grieve with all of Rochester. The FBI will continue to assist the Rochester Police Department and our law enforcement partners with this investigation. As always, anyone with information is encouraged to contact the FBI by calling 1800-CALL-FBI or submit a tip online at tips.fbi.gov.
