According to Durham Police, the victim was a passenger in a car that was on the freeway. They believe a person in another vehicle shot him while both cars were moving.
Investigators say the driver of the vehicle the victim was in then drove the victim to Durham Police headquarters, which was roped off as a crime scene.
It wasn't until they began interviewing the driver that they realized the Durham Freeway was the primary scene.
Police then shut down the northbound lanes of the freeway at Fayetteville Street for about five hours - snarling traffic.
The victim was rushed to the hospital. There is no information yet regarding the suspect or the suspect vehicle.
