One thing in this article stands out more than everything else:

Roy Barnes, 62, lives in Milwaukee. In 1999, he murdered the brother of one of Jeffrey Dahmer’s victims and received 45 years in prison for it. Barnes tortured the victim and used his ear as an ashtray, according to a 2000 Green Bay Press-Gazette article. In 1998, the article says, he committed “a hammer attack on another man.”

Evers’ administration paroled Barnes in September 2020.

This is now the third example of the "taking of a body part" connected directly to Dahmer. There is clearly a network of killers that practice the same form of witchcraft that the Mound Builders did. Unfortunately it's almost impossible to find any information on Roy Barnes or who his victim was using the internet because of how common his name is. Quite a few people named Roy Barnes have been murdered or murdered someone.

Do you know any information about this guy, or his victim, that I can look into?

Interestingly, there is another Roy Barnes who was himself dismembered right next to the Sarasota airport which we know is connected to the Royal Order of Jesters and SOBIB. The fact that he is also named Roy Barnes is probably just a coincidence, but it may not be coincidental that there was a dismemberment killing right next to the Sarasota International Airport.

Edit: I found some information. The victims name was Ernest Smith:

Ernest Smith’s killer ``posed″ the body, according to a medical examiner’s report. Figurines, which were not described in the report, were placed around the body and put in his hand.

Sheets from pornographic magazines were stuffed into his shoes and pants and cigarette ashes were put in an ear. The kitchen knife used to kill him was left in his body.
