The latest on the deadly Rochester crash

Rochester Police Chief David Smith detailed suspect Michael Avery's actions in the days leading up to the fatal car crash that authorities continue to investigate.

The 35-year-old man traveled to the area of Rochester, New York, in his personal vehicle on or about December 27 and checked into a hotel, Smith said.

On Friday afternoon, Avery rented a Ford Expedition from a car rental agency at the Rochester airport, the police chief said.

On Saturday, Avery made multiple purchases of gasoline and gas containers at various locations throughout the day, Smith said. It appears Avery made the purchases alone, he added.

Around 12:52 a.m. ET Monday — New Year's Day — Avery was driving the rented Ford Expedition near the site of a concert venue. Two Rochester police officers were working traffic after the concert ended, police said.

"At this time, Avery sped up, crossed into the ongoing lane of traffic, and appears to have intentionally been driving towards the pedestrian crossing,” Smith said Tuesday. At about the same time, a rideshare vehicle with two passengers in the back seat that was leaving the parking lot was struck by Avery's vehicle.

The two rear passengers of rideshare were killed, and nine pedestirans were injured, the police chief said.

Officials said the suspect in the crash has died and there is no indication of "political or social biases." Police continue to investigate the incident and a possible motive behind the crime.

Rochester Police Chief David M. Smith said Tuesday that suspect Michael Avery in the deadly Rochester car crash did not leave a suicide note or journal in his hotel room.

When asked what led police to believe the suspect was suffering from mental health issues, Smith said they had reached that conclusion based on conversations with his family.

Rochester Mayor Malik Evans said off-duty police officers sprung into action to try and help suspect Michael Avery, and put out a fire caused by the crash.

“Even in the midst of this despicable tragedy, there is a reminder that there is still goodness in this world of the individuals that sprang into action without thinking about their own safety to try to save others,” Evans said.

He also offered his condolences to the victims and their families.

Rochester Police Chief David Smith said police investigations so far have not uncovered any further evidence as to why suspect Michael Avery carried out the attack, but said conversations with family had led police to believe

“Avery may have been suffering from possible undiagnosed mental health issues," the official said.

He noted that authorities also had not found any evidence that suggested Avery’s actions “were motivated by any form political or social biases.”

The official also said there is no evidence at this time of another individual involved in the crime or that it was part of a "larger plot."

Special Agent in Charge Jeremy Bell from the local branch of the FBI said officials have not identified a nexus to terrorism. The FBI’s Joint Terrorism Task Force is investigating the incident, he said, but that is not abnormal.

Rochester Police Chief David Smith has confirmed that 35-year-old Michael Avery from Syracuse died overnight.

He said Avery traveled from Syracuse to New York on December 27.

Officials in Rochester, New York, are holding a news conference following a crash outside the Kodak Center Monday that is now being treated as possible domestic terrorism.

FBI officials are investigating the crash that killed two, and injured five others.

Authorities had warned of a “heightened threat environment” in New York ahead of New Year’s Eve.

A joint threat assessment based on an analysis from 10 law enforcement agencies — including the FBI, the US Department of Homeland Security and the New York Police Department — says the Israel-Hamas war “has created a heightened threat environment.”

But while the ongoing war has contributed to concerns about lone-wolf attacks, offiicals said there was “no specific reporting regarding any threats" prior to New Year's Eve.

Michael Avery, the suspect in the deadly Rochester car crash that is being investigated as domestic terrorism, has died, according to two law enforcement sources.

President Joe Biden has been briefed on the deadly car crash that plowed through a crowd outside a concert in Rochester, New York, a White House official says.

CNN previously reported the crash is being investigated as domestic terrorism, and the FBI’S Joint Terrorism Task Force is involved in the investigation.

Biden is set to return to Washington later today from his week-long vacation in St. Croix, US Virgin Islands.
