(Photos: The stained glass at the angle they first saw the shadowperson next to the "altar" thing--my son crouched to show the size of the thing. The second shot is the view they had when it peeked out at them--my son is standing in the shadowperson's spot to reenact it).
I definitely got distracted in paranormal research when I heard first-hand from my son his account of having seen a shadowperson. I have seen a couple myself that were person-height, and then finally saw a short one with my son on an investigation about a year ago. Because of this, I've become quite obsessed with what these are and what is occurring.
My son is one of those extremely level-headed, logic-minded, socially conscious types and to hear him tell what happened to him intrigued me greatly. He told his story on an audition tape for Ghost Hunters New Generation show and I only wish the tape could have been longer because he had to edit out the second half of the encounter with the shadowperson. (After having seen it, the boys went about 20' away to the left of the place they'd seen it and turned to see it actually peeking out of the edge of the window frame area at them. It was perhaps 3 or 3 1/2 feet tall. They realized it saw them and that freaked them out even more. They took off through the cemetery and headed back towards their car when the other boy saw it one more time). Here is the audition tape that recounts the shadowperson event.
