The Kershaw County Sheriff's Office says a female's former boyfriend confronted her current boyfriend in front of the Dollar General store in East Camden where she worked.
Witnesses say 24-year-old Marcus Dow of Camden pulled a knife on 21-year-old Trevin Johnson of Bishopville Thursday afternoon.
Johnson was stabbed in the head and body, and was taken to a hospital with life-threatening injuries.
The sheriff's office says Dow left the scene, but officers spotted and stopped his vehicle nearby and he told them he had a serious knife wound in the hand and was headed to a hospital.
Dow has been charged with attempted murder and was booked into the Kershaw County Detention Center on a $200,000 bond.
