Carrboro Police are still investigating the death of University of North Carolina student David Shannon, who fell to his death in October.
Lt. Chris Atack said the police are waiting for a toxicology report, which is due back in four to six weeks.
Atack said the police are still looking to see if the death was hazing related.
Police said it appears Shannon climbed on some machinery at the Ready Mixed Concrete Plant on Guthrie Avenue in Carrboro before falling about 40 feet.
Shannon, from Charlotte, had recently pledged a UNC fraternity.
