According to a sensationally-worded episode promotion on Facebook, the show will center on last Friday's search of Abilene's landfill, which turned up empty.
"Breaking now -- cadaver dogs reportedly hit on a possible scent at a landfill now closed off by police during the search for missing 13-year-old cheerleader Hailey Dunn. Have investigators found the missing teen cheerleader's remains? Nancy Grace live on the scene at 8 pm ET only on HLN."
The Nancy Grace show has followed the story since Jan. 3, giving national exposure to a missing person case that without an Amber Alert may not have been followed outside the West Texas region.
