There are still many unanswered questions about the fiery crash outside the Kodak Center on New Year’s Day.

Three people died and nine others were hurt when an SUV barreled into another car and then into a pedestrian crosswalk as a concert let out.

As long as it’s proven no one else was involved and the suspect acted alone, there will not be a trial as the suspect is one of the three people who died.

However, former high-level FBI Special Agent in Charge Peter Ahearn says that authorities will still work to get to the bottom of what and why this tragedy happened. 

“We learn from our past,” said Ahearn. “We have law enforcement professionals, psychologists, that look at the incidents to try to determine why somebody would do something like that to try to prevent something in the future and I think that’s important. Unfortunately, that’s hindsight and hindsight is 20/20. The event has happened. It has to be prosecuted, or, in this case the person is gone, but making sure there were no other motives or anyone else involved is critical.”

Ahearn says it’s critical to understand what triggered the suspect who Rochester police say caused the crash, Michael Avery.

Police say Avery rented a Ford Expedition at Rochester’s Airport and loaded it with several cans of gasoline. As he approached the Kodak Center shortly after midnight on New Year’s Day, they say he sped up. Police say his flaming vehicle slammed into a ride-share car that had just picked up two people. Police say Avery and those two passengers died while nine others were hurt.

Police add that Avery likely had mental health problems. 

The FBI says for now it does not appear to be an act of international or domestic terrorism.

But video has surfaced that the Rochester Police Department confirms shows the vehicle involved in the crash and a man who they believe to be Avery near the scene a short time before the crash.

Ahearn describes the significance of this and other possible corroborating videos.

"It goes to the fact that it’s a motive, but it's also planned and in this case, this is also an individual planning something like this, and you go out and you do the surveillance is what he was doing. You know, for what purpose? I think that kind of shows he was not as much mentally unstable. I mean he knew what he was doing. It goes to the premeditation of the incident. And that will be critical in the end of this, but, again, you have a dead [suspect, so] there’s not going to be a prosecution in this, but they’ll study as to why or what happened," said Ahearn.

Rochester police investigators continue to work with several police agencies as this investigation continues. They are seeking as many answers as possible to potentially prevent similar tragedies in the future.
