CHAPEL HILL - Investigators are following hundreds of leads but still don't know who killed UNC-Chapel Hill student Eve Carson, Police Chief Brian Curran said Tuesday.

Law enforcement officers have been looking at surveillance photos since Friday. Police on Saturday released photos from a local bank's ATM, then more from a local convenience store Monday.

Police are keeping some evidence private to keep an eventual suspect offguard and to weed out false confessors, Curran said.

People with information can call CrimeStoppers at 942-7515. The UNC-CH board of trustees has pledged $25,000 of its members' own money for information leading to an arrest in Carson's case.
