CINCINNATI -- Danny Dickson was stunned when he watched a car crash head-on into a tree in Walnut Hills Tuesday morning, but what he saw next left him even more horrified.

According to both Dickson and the Cincinnati Police Department, the car’s driver, 27-year-old Adriel Holloway, tried to walk away from the wreck, abandoning a child inside with life-threatening injuries.

“He was in the passenger seat,” Dickson said. “No seatbelt on. Just laying there, not making a noise. He wasn’t breathing.”

Police credited Dickson and other passersby with stopping Holloway as he attempted to flee on foot from the scene where the child still lay. Dickson said he followed Holloway up the road, blocked traffic with his car and called 911.

“As a human being, you can’t just stand here when something like that is happening and not try to help to make sure someone is okay,” Dickson said.

The child, Ariyonte Holloway, was taken to Cincinnati Children’s Hospital, where he is listed in critical condition. The elder Holloway was taken to University of Cincinnati Medical Center, where doctors described his condition as “fair."

Holloway was likely both impaired and driving too fast at the time of the crash, according to police.

Martin Luther King Jr. Drive was closed until about 1 p.m. as a result.
