A Knox County sheriff's chaplain in an unmarked car drove into the front a West Knoxville Weigel's gas station Tuesday afternoon, according to the sheriff's office.
Officials say 74-year-old Dennis Croucher drove an unmarked Crown Victoria into the Weigel's on Lonas Road.
A woman was transported to Tennova at Turkey Creek to treat minor injuries. The store also sustained heavy damage.
Croucher says his county car malfunctioned, causing the crash.
An investigation is underway.
