The citation issued to the driver of a sports utility vehicle that ran over a 4-year-old child in a stroller last week in Scottsdale has been dismissed, police said Thursday.

As part of the investigation, officers viewed the May 9 video from the red-light enforcement camera at the intersection at 90th Street and Shea Boulevard, police said.

Officers were called to the intersection about 1 p.m. after a black GMC SUV struck the woman and child as they were crossing Shea from north to south in the crosswalk, police said.

While they were in the crosswalk, the traffic signal changed to green for the eastbound vehicle, police said.

In the video released Thursday, the SUV driver appeared to have the view of the crossing pedestrians partially obscured by a large-profile vehicle. The SUV began to move on the green light at the same time the mother and child emerged into the SUV's path, police said. The video shows the mother apparently picking up her pace to make it across.

The SUV rolled over the stroller and child, but the child was not seriously injured. The mother also was not injured.

"The video shows the pedestrians run into the path of the vehicle that was so close that it was difficult for the driver to yield," a police spokesman said. "Given the new evidence presented by the video, the investigating officer has requested the original citation given to the SUV driver be dismissed."

In Arizona, there are more than 1,500 pedestrian-vehicle collisions every year, police said. Scottsdale police warn pedestrians not to assume drivers see them and make sure to allow enough time to safely cross multi-lane streets.
