A Cumberland County teen was killed in a multiple-vehicle crash on I-40 Monday afternoon. Ian Honcoop, 17, was traveling I-40 East when, according to witnesses, a vehicle stopped suddenly to cross over from Eastbound to Westbound which caused a lock-up of other vehicles on the interstate. Ian crashed into a semi-truck due to the lock-up and was killed instantly. Ian was a senior at Stone Memorial High School. An investigation is ongoing by the Tennessee Highway Patrol. Ian’s mother posted this on Facebook: “Don’t be that person who thinks that an emergency (crossover) lane is for their use. My family lost part of it’s heart tonight due to the entitled thinking of one person.”
