Zachary and Katherine Barton, both 39, of Arlington, were killed in a five-vehicle chain-reaction crash on State Highway 171 north of Hillsboro Saturday night, according to DPS. Investigators say people who got out of their vehicles after the initial wreck were standing in the roadway when another vehicle struck them. A 12-year-old and another driver were critically injured. The couple met at the International Bowling Campus, and friends say they leave behind two young children. #Arlington #NorthTexas #Hillsboro
