This is him:
I found a google cached dox of him and they have everything on him, including his username here. He appears to know jim and azien, from the chat search on this site.
The tip the police had was very likely the dox I found. I won't post the dox tho.
They have a pic of him as well and his name in the dox and it is indeed him.
Can you tell me who these people are?

The discord link does not work and the twitter I found looks dead. They hacked and doxed him. Not sure if they send the tip to the police, but they produced the tip/dox.
