-- Investigators hope a note scribbled on the back of a fast food bag leads them to whomever killed a University of North Carolina Chapel Hill student two years ago.
Police say that despite a 300-page case file and traces of the killer's DNA all over her apartment, they're still nowhere closer to finding whomever killed her.
"What we lack now is that key piece of information that can help us connect the strong case with the killer," Chapel Hill Police Chief Chris Blue said.
The body of Hedgepeth, a member of the Haliwa-Saponi tribe of Hollister, N.C., was found at her off-campus apartment by friends who police have not identified. The biology major had spent the previous night at the library before going to a bar with a friend, police said. She was last seen at her apartment around 4:30 a.m.
Police ruled out the act as a random killing.
Hedgepeth's father has been conducting his own investigation.
"I know that as long as I have breath, I won't stop looking," Roland Hedgepeth said. "I hope maybe someone saw her when they arrived back at the apartment ... I'm just trying to trigger some things in people's minds to help them think that no detail, nothing that you may have seen is too little to report."
Police are confident that someone will come forward with a new lead.
"If the killer is out there hearing this message, we will catch you," Blue said.
Police have asked persons of interest to provide DNA swabs to compare to the DNA left at Hedgepeth's apartment but have found no matches. Police say it is likely that she knew her killer, who may have left the area suddenly after the crime.
