The man accused of killing a woman who got into his car thinking it was her Uber ride had turned on the child locks in his back seat so the doors could be opened only from the outside, police in South Carolina say.

Columbia Police Chief Skip Holbrook said investigators found the victim's blood in Nathaniel David Rowland's vehicle. Rowland, 24, was arrested and charged in the death of 21-year-old Samantha Josephson of Robbinsville, N.J.

Investigators would not say what they thought Rowland did to Josephson from the time she got into a black Chevrolet Impala in Columbia's Five Points entertainment district about 1:30 a.m. Friday until her body was dumped in woods off a dirt road in Clarendon County about 65 miles away.

Josephson had numerous wounds to her head, neck, face, upper body, leg, and foot, according to arrest warrants released Sunday by the State Law Enforcement Division. The documents didn't say what was used to attack her.

Josephson's blood was found in the trunk and inside Rowland's car along with her cellphone, Holbrook said, as well as bleach, window cleaner, and cleaning wipes.

"This was a bad scene," the police chief said at a news conference late Saturday.

Hunters found Josephson's body Friday afternoon just hours after it was dumped despite being left in an area that was "very difficult to get to unless you knew how to get there," Holbrook said.

Rowland recently lived in the area, Holbrook said.

The night after Josephson was kidnapped, a Columbia officer noticed a black Chevrolet Impala about two blocks from the Five Points bars where Josephson was taken. The driver ran but was arrested after a short chase, Holbrook said.

Rowland is charged with kidnapping and murder, Holbrook said. He was being held in the Richland County jail. It wasn't known whether he had a lawyer.

Safety advocates urged college students to match the vehicle color and model, the license tag number, and the photo of their ride-share drivers before getting in a vehicle.

"She simply, mistakenly got into the car thinking it was an Uber ride," Holbrook said.

The crime shook Columbia, the state capital where the University of South Carolina is one of the main economic engines. Josephson was a student at the school.
