>>1845 (OP)
see if you can get a few of his books online. they contain all the cases he refers to in radio shows etc. also, he's done a bunch of radio interviews on C2C going back to 2012. the ones with George Knapp are the best.
i think he's picked up on a whole bunch of different things which are going on out there, from normal cases of children just wandering off, to attempted kidnappings to the few examples which pretty much have to be portals or whatever. His criteria for including a case is still too wide to really narrow it down, so the data is very mixed.
