Three people, two of them children,  were  injured in a two-vehicle crash just inside the city limits of Alexandria on Highway 70 Monday afternoon. According to Trooper Bobby Johnson of the Tennessee Highway Patrol, 57-year-old Litta Murphy of McMinnville was traveling west in a 2003 Ford Taurus when she experienced some sort of a medical problem, causing her to cross into the east-bound lane. She then struck a  2004 Ford F250 driven by 71-year-old James Wair of Lebanon. Murphy's granddaughters, six and seven years old, were passengers in the back seat of the Taurus. The seven-year-old was transported to a helicopter landing zone on Highway 53 by DeKalb EMS and airlifted to Vanderbilt Medical Center. The six-year-old girl and her grandmother were transported to DeKalb Community Hospital by DeKalb EMS. The six-year-old was later taken  Vanderbilt by ambulance. Wair was taken by a private vehicle to UMC Medical Center in Lebanon. The trooper said Murphy was to be cited for violation of due care. The Alexandria Police Department assisted on the scene, and the Alexandria Volunteer Fire Department set up a landing zone for the helicopter.
