The video is hard to see, but shows what appear to be a couple gun flashes right away.
Lilly is expected to make his first court appearance on Friday. Lilly is then seen stepping out of his vehicle, a black Toyota sedan, and walking back to confront the driver of the school bus.
According to a criminal complaint, Minneapolis police officers were called to a shooting Tuesday on Interstate 35W near Chicago Avenue.
An investigation revealed that the bus driver was merging onto the interstate when he collided with Lilly's sedan.
"We nearly start running out of ways to describe this".
"The filing of the complaint tells you that we do not believe there was a self-defense claim based upon the evidence we have received so far", Chief Deputy Hennepin County Attorney David Brown told reporters. "It is just horrific".
Lilly was wearing a security guard's uniform at the time of the shooting.
In a blurry video of the incident released by the Minnesota DOT, a man who is allegedly Lilly gets out of the vehicle and walks back toward the bus, which is halted in traffic on the highway. The company's president, Troy Nadeau, said he doesn't know where the violent behavior came from, adding that Lilly "had a clean file", and was "a good guy who was always on time".
According to the complaint, Lilly stopped his auto in the lane of traffic and walked toward the bus.
His gunfire grazed the side of the driver's head and struck his left arm.
This is the horrifying moment a man opened fire on a school bus driver during a road rage clash on a snowy American highway.
Lilly told officers he shot at the driver because he feared for his safety.
