Tennessee police this week arrested a second suspect in the shooting death of a nurse who was shot to death last month while driving along Interstate 440 on her way to work, WKRN reports. James Edward Cowan, 28, was arrested Tuesday night as he arrived at the Hickory Hollow Place apartment after they followed him from a motel where he’d been staying for several days. As CrimeOnline previously reported, a Nashville Parks police officer saw Caitlyn Kaufman’s car against a guard rail off the highway on the west end of the city shortly before 9 p.m. on December 3. He stopped to assist, thinking it was a single-car accident, but instead found Kaufman with at least one gunshot wound.
