Chapel Hill Police Chief Brian Curran said Monday night that the man was the only person in the store when the ATM card was used.
Originally, authorities said they believed the person in the store and in the car were the same man. Curran corrected that information this afternoon, announcing that Lovette was caught in the drive-through ATM tape and Atwater was seen entering the convenience store.
The UNC board of trustees had offered a $25,000 reward for information leading to an arrest and conviction in Carson's killing. The pre-medicine double biology and political science major also served as a board member.
Search warrants filed in the case revealed that police found Carson's cell phone near a shopping center on the road that connects the towns of Chapel Hill and Durham. Authorities have not recovered her wallet or keys and are searching a student laptop and memory cards from her campus office.
