(Lewisburg, OH)--A Richmond man was killed in a crash on I-70 in Preble County Sunday. 29-year-old Andrew Adkins was headed west on 70 near Lewisburg when he slammed into the back of a semi that had slowed for a previous crash. "We don't have any indications that there was any pre-crash braking or anything like that on the part of the passenger vehicle. He probably was not paying attention," said Chris Colbert with the Ohio Highway Patrol. Adkins was pronounced dead at the scene. His wife, Christine, was flown to Miami Valley Hospital in Dayton. She was in serious condition Monday morning. The couple’s two children suffered relatively minor injuries.
