CHAPEL HILL -- Police are still working to identify a person of interest in the investigation into the killing of University of North Carolina student body president Eve Carson. The 22-year-old's body was found Wednesday with multiple gunshot wounds on a street near campus.

A picture released this weekend shows a man using Carson's ATM card while possibly driving her SUV, and now police say he might not have been alone in the vehicle. According to the Raleigh Chronicle, the picture shows a shadowed figure behind the driver's head rest, which police say could be someone else's shoulder.

Police have not confirmed if there is a second person nor have they said where or what time the ATM photo was taken.

Family, friends and loved ones gathered Sunday in Georgia to say goodbye to the slain student leader. UNC Chancellor James Moeser was among the hundreds of mourners on hand for the service. Many wore Carolina blue ribbons in her honor.

The minister who spoke at the funeral expressed his anger that Carson isn't enjoying spring break or getting ready for the ACC basketball tournament.

Anyone with information about Carson’s death is asked to call the Chapel Hill Police Department at (919) 968-2760. All calls are confidential and a $25,000 reward has been offered for information leading to an arrest.
