A 25-year-old man was killed early Saturday morning when he was struck by a Ford Explorer while trying to cross  I-75 on foot.

Marietta police said Andre Blickenstaff, of Canton, was attempting to cross I-75 between North Marietta Parkway and the Canton Road Connector in Cobb County at about 2:54 a.m. when he was hit in northbound lanes by an SUV driven by Charles Severtson, 50, of Dallas.

Mr. Severston stopped and called 911.  Blickenstaff was pronounced dead on the scene. Police said no charges are  expected against Mr. Severtson. Investigators are still trying to figure out why Blickenstaff was crossing the interstate.
