A late night traffic stop Wednesday in Seneca led the police to confiscate crystal methamphetamine, cash, and other items. The police say the driver, Larry Neil Gibson, Jr., 47, of Cottontail Drive, Westminster, was charged with meth trafficking. A policeman said erratic maneuvers on By-Pass 123 in the vicinity of the overhead bridge prompted him to follow a Buick automobile and stop it in the parking lot of a drug store. It was there, the officer said, that an item was thrown into a bed of mulch. The police say they opened that item and found 33 grams of meth. The police also confiscated $1,100—seized in what police believe were proceeds from trafficking.
