Haley Smith was walking with friends on Kenton Morrison Road around 8:30 p.m. Nov. 16 when a driver plowed into her and kept driving.
Deputies said the truck was last seen driving on Holmes Boulevard.
Investigators found the passenger side mirror from the suspect vehicle at the scene of the crash. The mirror was an aftermarket reproduction mirror that could fit different types of small pickup trucks and SUVs.
Deputies said they are looking for a small pickup with an unknown color that should have damage to the
passenger side headlight area and a missing or recently replaced passenger side mirror.
