CHAPEL HILL - The UNC-Chapel Hill Board of Trustees paid $25,000 in rewards for tips that led to the arrests of Eve Carson's alleged killers. Now the governor's office is offering $10,000 more.

Gov. Mike Easley pledged Wednesday to pay $10,000 for information leading to the arrest of anyone who may have harbored or otherwise supported Demario James Atwater or Laurence Alvin Lovette Jr. after Carson's slaying March 5.

"It is believed that further information may exist that could possibly implicate others as accessories after the fact," Easley said in a statement. "To preserve law and order, the person or persons who committed such an infamous crime must be brought to justice."

Chapel Hill Police spokesman Lt. Kevin Gunter said he doesn't know of any additional suspects in the Carson case and couldn't identify them if he did. "There may be other potential suspects out there that we might be looking at," Gunter said. "Because it's part of the investigation, that would be information [investigators] wouldn't share with me."

Gunter said he didn't know who received the trustees' $25,000 reward, which came from their personal funds, or how many different people may have split it. He said he had never heard of the governor offering a reward in another case. "It's just a cry for help from the citizens," Gunter said.

Carson, UNC-CH's student body president, was found shot to death in the street of a neighborhood off East Franklin Street, near campus. Police said she had been shot several times, including once in the right temple.

Lovette, 17, and Atwater, 21, were both charged with first-degree murder after surveillance photos showed them trying to use Carson's bank or credit card at a local ATM and a convenience store, according to police. Lovette is charged also in the January slaying of Abhijit Mahato, a Duke University graduate student. Probable cause hearings in both cases are scheduled for next week.
