AURORA | A three-car crash Sunday afternoon at Hampden and Buckley left 12 people injured, two seriously, according to Aurora police.

Investigators said the crash occurred at about 2 p.m. when a silver Saturn SUV was turning left from westbound East Hampden Avenue onto southbound South Buckley Road. As the car was turning, the Saturn was struck broadside by a Honda sedan traveling eastbound on Hampden.

A female in her twenties riding in the back seat of the Saturn was thrown from the car and was critically injured. The impact of the two cars resulted in the Saturn striking another car that was stopped on northbound Buckley.

Inside the Honda were four children, one of whom was also critically injured, police said. It appears none of the children were properly restrained inside the car, according to reports.

Police have not yet determined who was at fault in the crash, but they did say neither alcohol nor speed were factors in the incident.

“As the two most critically injured people in this crash were not wearing seat belts, the Aurora Police Department implores citizens to use seat belts and properly restrain children whenever traveling in vehicles,” said Aurora police spokesman Chris Carleton. “It is likely the injuries in this crash could have been avoided or at least reduced had seat belts and child safety seats been used.”
