Possible scenario:
They decided to be adventurous 12:15 and went to the lake. They dinked around by the shoreline or something (TG passed through, but didn't see them, just the bikes in the trail so he had to swerve)...then they headed back toward home...they realized they forgot the purse and went back to get it (seen by the watering couple)...They parked the bikes this time against the fence...and kablambo something happened, including running or being chased or carried into the woods (dogs tracked them at the shoreline and into the forest)..MOO
