"At some point, the individual in the white SUV drove up to the right side of her vehicle, at which time one gun shot was fired," said Assistant Chief Mark Herman with the Harris County Precinct 4 Constable's Office.
The driver shot through Hafford's passenger side window, hitting her in the back of the head. Hafford was taken to the hospital where she was treated for her injuries.
Kendrick Hafford, her husband, says she didn't need surgery, but did suffer head trauma.
The search continues for that white SUV and a man wearing a blue baseball cap.
