DENVER -- People in downtown Denver are still trying to figure out what they saw after a bizarre car accident Monday afternoon.

Around 2 p.m., witnesses said a boy about 5 years old fell out of a silver or white van that was traveling westbound on 13th Avenue between Pennsylvania and Logan streets. The back tire reportedly ran over part of the child.

“I was working up in my office and heard a thud and a scream,” witness Brian Bandimere said.

The vehicle stopped in the far right lane of 13th Avenue just west of Pennsylvania Street.

“There was a lady out in the street kind of behind her minivan and she was holding her child and picked him up and put him in the car,” Bandimere said.

A customer at a nearby tavern called 911.

“Did [the child] look OK?” Bandimere was asked.

“No. Obviously not. I mean he was being held by his mom but from what I could tell it didn’t look good,” he said. “I didn’t see him move, but I didn’t see any blood either.”

Witnesses said the incident took a strange turn seconds after the accident. The woman who was caring for the child reportedly picked him up, put him back in the vehicle and drove off.

“When she picked him up and put him in the van, I couldn’t put the two and two together. And then to see him leave, I just thought that doesn’t seem right,” Bandimere said.

Police dispatched officers in pursuit of the vehicle but were unable to locate it. A police department spokesman said they checked several hospitals, but none had any patients matching the boy’s description.
