State Police are searching for a suspect who allegedly stole a pickup truck at a gas station in Epsom on Monday. Trooper says the black truck with a toolbox in the back disappeared from the Cumberland Farms on Dover Road near Route 4. It was spotted in Concord and pursued into Salisbury but fog and rain in the area forced officers to stop. The truck was last seen heading westbound on Route 4 toward Andover. Authorities said the driver is described as a white man with a goatee wearing a black vest.
