WALTON COUNTY, Ga. -- Gwinnett County Sheriff Butch Conway says authorities know who is behind the disappearance of a teenager missing for nearly eight years.
Justin Gaines disappeared in November 2007 after a night out in Gwinnett County. Over the years, authorities have received several tips, but none have panned out.
When asked if authorities know who is behind Gaines' disappearance, Conway said, "We do. And we've known for some time. We've got to prove it."
