A passenger was killed today when a car rolled over and he was thrown from the vehicle in northern Delaware, police said. The driver suffered non-life-threatening injuries.

Delaware State Police said Candace Carhart, 20, was behind the wheel of a 2007 Mazda 6 about 2 a.m., driving southbound on Lancaster Pike in Hockessin when she came to the split with Route 48.

Carhart started to enter Route 48 and then swung right to get back on Lancaster Pike. She ended up on the grassy median, where the car rolled over several times, police said.

Her passenger, who was not wearing a seat belt, was thrown from the car, police said. He was rushed to Christiana Hospital, where he was pronounced dead. His name has not been released.

Carhart, of Wilmington, who was wearing a seat belt, also was taken to the hospital for treatment of what police described as non-life-threatening injuries.

No charges have been filed, but police said alcohol appears to have been a factor in the crash.
