Police think there may have been a second person in the vehicle driven by a man they say was trying to use the ATM card belonging to a slain University of North Carolina student from Athens, a North Carolina newspaper reported Sunday night.

"We believe there may have been a second person in the vehicle," Chapel Hill, N.C., Police Chief Brian Curran told The News & Observer of Raleigh.

Chapel Hill police detectives are searching for this man, photographed using the ATM card of Eve Carson. Carson, 22, of Athens, Ga., was found shot dead Wednesday morning lying on a street about a mile from campus.

Eve Carson, 22, a 2004 graduate of Clarke Central High School in Athens and the UNC student body president, was found shot to death early Wednesday morning less than a mile from her home in Chapel Hill.

Her sport utility vehicle was discovered Thursday, a few hours after police positively identified her as the victim. Police said she likely was the victim of a random crime.

Detectives have been searching for a man photographed using Carson's ATM card, releasing photos on Saturday of the suspect at an ATM machine in Chapel Hill.

Black and white photographs distributed at a news conference show what looks to be a large, shadowed figure behind the driver's side head rest. What looks like someone's shoulder can be seen between the driver's seat and head rest.

Police have said the SUV in the surveillance photo could be Carson's blue 2005 Toyota Highlander. If there was a second person in the back seat, it could explain how the killer or killers got away. The SUV was found parked around the corner from Carson's downtown Chapel Hill home.

Neither Curran nor his spokesman, Lt. Kevin Gunter, immediately returned a message from the Associated Press seeking comment Sunday.
