The man whose stepson was killed in that freak accident on I-20 on the Westside of Atlanta still can’t wrap his head around what happened.

“I don’t really believe he’s gone yet,” Quantain Malone told Channel 2 Action News. “He loved to play. He loved to be the big brother to his little sisters. He was like an old man in a little kid’s body.

8-year-old Cameron Mcilwain was killed when he was hit with part of a transmission that flew off a tractor-trailer on the other side of the interstate.

Before the debris hit Mcilwain, it also hit his mother Jameka French. She was driving the SUV when the metal came through the windshield. Part of her arm had to be amputated.

"She had her hand by her face, and it came through the windshield, went through her arm, hit Cameron and went out the back window in the truck," said Malone, French's husband. "It happened so fast."

French’s other 19-month old child was injured by the shattered glass but not seriously hurt.

The GSP is investigating to see if anything could have been done to prevent this.

“There is a possibility charges could be filed,” said Gordy Wright with the Georgia State Patrol. “Or this could end up being a very freak tragic accident.”

The tractor-trailer driver, David Washington, 52, was working for CW Transport when the incident happened.

“In the situation like this, where it appears there was mechanical failure, officers are going to conduct a full inspection on the tractor-trailer to determine if there were other violations,” Wright said.

I-20 was closed in both directions for about three hours Wednesday evening. The westbound lanes re-opened just before 10 p.m.

Three other vehicles hit debris in the roadway in the westbound lanes of I-20, but no one was hurt, Wright said.
