Denver police Lt. Robert Rock urged the female driver of a hit-and-run Wednesday to turn herself in.

The 16-year-old victim of the crash sustained a serious head injury when she was struck in a crosswalk on East Colfax Avenue near Elizabeth Street in front of East High School just after 7 a.m. Wednesday. The woman — described as white or Hispanic in her 20s or 30s with shoulder-length red hair — kept going east on Colfax, as numerous witnesses watched.

Surveillance video indicates the sedan ran a red light.

The car was described as a gray or metallic colored four-door sedan with damage to its front passenger side, Rock said.

A few minutes later, another East High student was hit nearby when the 14-year-old ran into traffic at East Colfax Avenue and Fillmore Street. The driver remained at the scene, police said.

That student was being treated at a hospital for serious injuries.

Crime Stoppers is offering a $2,000 reward. Anyone with information is asked to call Crime Stoppers at 720-913-7867.
