There's some smoke here. A little timeline from what I remember.

Earlier that week, a local agitator got into it with the Republican Mayor of Jacksonville on Twitter. Mayor Curry is known for his late night drunken angry tweets (aren't we all), and I retweet a screenshot if it for posterity. Basically, the agitator was hinting that Stermon had recently lost his unfettered access to the Sherrif's office, and Curry was quick to go out of line and call Stermon a friend while telling the reporter to "Pound Sand Chump."
After I retweet it, I get a text from a coworker who saw that exchange and says he knows Stermon, used to live down the street from him. He's a creep, didn't trust his daughter around him. Also, he was Facebook friends with him and he had become unhinged, some long ranting posts asking DeSantis for help. Two days later, a few hours before the media reported it, the coworker informed me about Stermon's suicide. Something's up. I don't believe this is a murder cover-up situation. Post offices likely have surveillance.
Stermon was more than a donor, as the article details.
