A very good article talking about who he was.
Milwaukee community fixture who supported Trump and BLM murdered in front of own store
While it says the don't know if it was politically motivated, he was very politically active, and had Trump 2020 signs on the front of his store, so I suppose it could be possible.
According to the article, he was an important part of the community, so what doesn't make me wonder is whether the murderer should be punished under the law, but why he would take that man's life specifically.
I'm not a Trump supporter, but respect others' opinions, and can't even start to understand how a difference of opinion would lead for one person to kill another, especially given his ties to the community.
Very tragic.
