Henderson firefighters responded to a rollover crash on Thursday.

Investigators say a Buick vehicle pulled out of a private driveway and clipped a Dodge Town and Country causing it to rollover.
The female passenger of the Town and Country was partially ejected and transported to Sunrise Trauma in stable condition, but with critical injuries.
This crash is being investigated as a hit-and-run. The vehicle that caused the crash fled the scene.
Henderson police are looking for a gray four-door Buick sedan with significant damage to the front end.
