Boy attacked by non-humans in North Dakota

I just read the whole story and the hypnosis session and it's pretty crazy. The kid sounds genuine and doest really call them aliens or spacemen, he just calls them guys. Amazing story. But if the kid saw the creatures going into the barn, wouldnt the cops or the family be looking for tracks? You'd think that 4-5 creatures would leave at least some trace evidence.

I'm not sure what the laws are in ND but in most farming states you can legally shoot a poacher/trespasser. The kid's single-shot 22lr is a pretty reasonable rifle for a 16yo --- a simple varminting/plinking gun --- a good choice on a farm. Too bad he didn't have a .308

Didn't read all the posts, but the initial link is dead and from the
readers accounts on pg1 and this page, seems legit, anyone care to
explain what these critters might of looked like?
