North Carolina police are searching for the suspects responsible for shooting and wounding seven people in what authorities believe to be a "large exchange of gunfire" on roadways in Winston-Salem. 

The gunfire erupted around 7:50 p.m. Sunday when Winston-Salem police officers responded to multiple reports of shots fired in the 900 block of Bethlehem Lane, near Fairview Park, WXII reported. 

Upon arrival, officers found over 50 spent shell casings from different caliber weapons both in the road and in the park. As police were at the scene still investigating, another report came in about two gunshot victims nearby on Highway 52 North just south of the 25th Street Exit.
