I listened to that first video by Wolfgang. Interesting stuff how he was trying to find out information on who had the contract to deliver milk to Sandy Hook, etc. (He never got the records). He was trying to show that the school wasn’t in use at the time. (From the few photos of the school I would tend to agree - looked like it was being used for storage).
I did a search on Wolfgang, and the last thing I could see about him was that he had been arrested for having information on him about one of the parents (soc. security number, etc.) I think it was the parent that was seen laughing and then we he realized he was on camera put on his sad face.
