Who were the two shadows running into the woods? If one was a cop, then who was the other, and why did he run?
Post #32 answers that.
He was the guy on the cell phone to 911 outside the school who told them about the broken glass in front and the gunshots in the school.
It turned out to be a parent of a student in the school who foolishly ran when he saw men with guns coming after him.
He was the one chased up into the woods and handcuffed -- a waste of valuable time.
