The never-before-seen full video of the so-called "Bridge Guy" who was trailing two Indiana girls before their brutal murders ...

The chilling video footage of the final moments before two teenage girls were brutally murdered has been released for the very first time.

On the hike, Liberty shared a photo of Abigail crossing a bridge on Snapchat. Their bodies were found less than 24 hours later — less than a mile from where they were last seen alive.

The “full, raw” 43-second video was recorded on German’s Snapchat while she and Williams walked on Delphi’s Monon High Bridge on Feb. 13, 2017, before the Indiana teens were killed.
