North Carolina ? Detectives are searching for a man photographed using the ATM card of the University of North Carolina student body president found shot to death on a city street, police said Saturday.

Chapel Hill Police Chief Brian Curran released two surveillance photos of the suspect taken at an ATM machine in Chapel Hill, but declined to say when or exactly where the photos were taken. Police also released a photo of a baseball cap the suspect appears to be wearing in both of the surveillance pictures.

“This is our biggest break so far in this case,” Curran said.
