Justin Gaines, 18, of Snellville, went missing after leaving Wild Bill's Night Club in Duluth five years ago.
The Night Club was packed with college students Nov. 1, 2007.
Now Gaines' mother and the private investigator working the case told CBS Atlanta News that they have a new tip in his disappearance.
They are hoping to connect that lead with a tip that was called in nearly five years ago.
The last known image of Gaines was taken from a surveillance camera outside the night club. In it Gaines can be seen walking out of the camera's view, never to be been again.
Back then family, friends and even the National Guard searched for Gaines and didn't find him.
But now his family has new hope.
Private investigators Bob Poulnot said someone called in an anonymous tip in the past few weeks which seems to back up a tip an anonymous woman called in shortly after Gaines went missing.
"With the information we've gotten recently from a separate tip, sparked our interest in what she had to say five years ago," Poulnot said.
Poulnot and Gaines' mother, Erica Wilson, are hoping the woman who called in five years a go will call in again.
"We're not going to find him without the public's help to bring in new leads. When I hear about it [the new tip] I have hope. It gives me more hope," Wilson said.
Anyone with information about Gaines' disappearance can call Gwinnett County police at 770-513-5387 or Texas Equusearch anonymously at 1-877-270-9500.
