COLUMBIA, S.C. (AP) _ Police arrested a man Saturday in connection with the death of a college student who apparently got into the suspect's car thinking it was her Uber ride. Now they're saying a sharp object was used to kill her.

• Nathaniel David Rowland, 24, was arrested early Saturday after a police officer noticed him driving a black Chevy Impala, the same type of car that Samantha Josephson got into as she left a bar shortly after 2 a.m. Friday
• Rowland tried to run, but the officer was able to catch up to him
• Rowland will be charged with murder and kidnapping

Nathaniel David Rowland, 24, was arrested early Saturday after a police officer noticed him driving a black Chevy Impala, the same type of car that Samantha Josephson got into as she left a bar shortly after 2 a.m. Friday in the city of Columbia's 5 Points area, Columbia Police Chief Skip Holbrook said at a news conference. 

Rowland tried to run, but the officer was able to catch up to him, Holbrook said. When they returned to the car, he said, the officer saw what appeared to be blood in the car. 

"We believe ... that she simply mistakenly got into this particular car thinking it was an Uber ride,'' Holbrook said of Josephson, noting that surveillance video captured her getting into the car. "She opened the door and got into it and departed with the suspect driving.''

Arrest warrants say after Josephson got into his car early Friday, Rowland attacked her, causing numerous wounds to her head, neck, face, upper body, leg, and foot.

Rowland will be charged with murder and kidnapping, Rowland said. It was unclear if he had an attorney. 

Holbrook said hunters found Josephson's body late Friday afternoon off a dirt road in rural Clarendon County, which is about 65 miles (105 kilometers) southeast of Columbia.
