On Thursday, prosecutors charged him with attempted murder and assault with a risky weapon. They say additional calls described a male outside of a auto pointing a gun at a school bus, and that subsequent callers said shots were being fired. He's due in court Friday and remains in the Hennepin County Jail.
This is the horrifying moment a man opened fire on a school bus driver during a road rage clash on a snowy American highway. The 78-year-old male is now recovering from non-life-threatening injuries after being shot in the head and left arm.
According to prosecutors, Lilly called 911 after firing the shots and was arrested at the scene.
"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.
Lilly was wearing a security guard's uniform at the time of the shooting. Suddenly, the suspect's vehicle pulls into the hard shoulder.
Officials said the bus driver stayed awake as he was taken to a nearby hospital and is doing OK.
Law enforcement authorities responded to a report of a shooting on the interstate at Chicago Avenue in Minneapolis at 2:14 p.m. Tuesday. That's when he steps from his vehicle and walks back to the school bus and begins shooting into the windshield.
However, the video footage showed the defendant had retreated to a safe spot before walking in front of the bus and shooting, according to the complaint.
Lilly apparently told troopers that he feared for his safety as he approached the doorway of the bus.
The school bus driver, who wasn't identified, suffered a gunshot wound to the head and was expected to survive.
