A pickup truck, stolen late last week from the parking lot of a Westminster drug store, remains unaccounted for today, but the police chief says an active investigation into the theft remains in progress. Chief Dean Awalt says the 1994 two-tone green Ford F-150 displayed a South Carolina tag of 4-9-6-F-G and contained someone’s personal papers. According to Awalt, the keys were left in the truck when it was stolen between 1 and 2 o’clock Friday afternoon from the parking lot of Rite-Aid.
