Aaron Dunigan, an 18-year-old senior at Illinois' Thornton Fractional North High School, was killed in a car accident early Saturday morning, when a car he was riding in went over a median and crashed into another car, reports NBC Chicago. Aaron and the driver of the other car, 56-year-old Juan Jose Rivera were the two casualties of the accident.
The driver in Aaron's car, David Peden, was charged with reckless homicide and aggravated DUI resulting in death. Another teen passenger in the car, Mike Crowter, survived with serious injuries.
Aaron's mom, Katherine Jackson -- who never graduated herself -- opened up to NBC Chicago on her decision to walk for her late son.
"[Aaron] knows his mom never walked the stage," Katherine said. "I'm going to be his legs and he’s going to be my wings and we're going to go up there and get our diploma."
