The deceased student, Daniel S. Walker of 92 Pine St. in Carrboro was a student in UNC's School of Journalism and Mass Communication.
Carrboro Police Capt. Joel Booker said Saturday that officials were concerned the use of tainted drugs might have contributed to Walker's death.
"There's concern over possible drug use and the possibility of an overdose or that there could have been some tainted drugs in the area," Booker said.
"We're not trying to alarm the community. But we're trying to make folks aware this potential exists."
Booker said police were not certain what type of drugs Walker might have used or even if any drugs were used at all.
The State Medical Examiner's Office in Orange County performed an autopsy on Walker this weekend and determined that there was no foul play involved in his death, Booker said.
Because drug use was suspected, Dr. Tom Owens, assistant medical examiner and pathology resident, said certain tests were run -- the results of which should be available in a few weeks. "They won't know until they get toxicology reports back," Owens said.
"That usually takes weeks. It'll probably be a month and a half before any word is settled on."
Carrboro police will continue to investigate the incident.
