A single car accident overnight took a twist when a second accident happened.
Shortly after midnight Friday, Wichita Falls police were called to Southwest Parkway and University Avenue for a single car accident.
A female driver slammed into a tree as she swerved to avoid hitting a dog. The driver complained of chest pain and was transported to United Regional with non life-threatening injuries.
While police were investigating that accident, another car hit the back of an empty patrol vehicle.
