COULD THE INVESTIGATION INTO WHAT HAPPENED TO A GEORGIA TEACHER AND FORMER BEAUTY QUEEN HAVE BEEN SOLVED YEARS AGO?

"48 Hours" Investigates in an Encore of "The Tara Grinstead Mystery"

48 HOURS: "The Tara Grinstead Mystery" (10:00 PM)

48 HOURS and Peter Van Sant investigate the disappearance of Tara Grinstead, a Georgia teacher and former beauty queen who seemingly vanished overnight in October 2005, in an updated encore of "The Tara Grinstead Mystery" to be broadcast Saturday, August 20 (10:00 PM, ET/PT) on the CBS Television Network and streamed on Paramount+. 48 HOURS reports how the case was broken open by a surprising confession - nearly 12 years after Grinstead disappeared - that ultimately led to the arrests of two men. But could the case have been solved earlier? John McCullough, who maintains he tried to give investigators a key tip in 2007 that could have cracked the case, speaks out on 48 HOURS.

48 HOURS is broadcast Saturdays at 10:00 PM, ET/PT on CBS, and streams anytime on Paramount+. There's also a new way to watch 48 HOURS.
