This guy, Matt, used to be part of a podcast community on Discord that I am a part of. He went by the name "PodcastHitman", and was a constant contributor to the podcast "Who Are These Podcasts", where he supplied the host with audio clips and information about another guy, who the host still mentions on the show to this day. Matt was very obsessive and possessive over this other guy.
At some point last year, I'm not sure when, I'd have to go find the exact episode, he had mentioned that he likely wouldn't be contributing anymore, as he was getting "serious" in his relationship. The host jokingly responded that he hopes the relationship doesn't work out, so Matt can still contribute to the show.
Then one day, likely very soon after the murder, though I'm not sure of the exact date, Matt started contributing again, acting as though nothing had happened. No one pressed him on it, as it wasn't seen as a red flag yet.
It wasn't until just last week, at the end that week's episode of another show, titled "The Creep Off", that the host of "Who Are These Podcasts" talked about it, having only found out the day before the episode.
The group is still piecing things together, seeing if we can try to pinpoint the exact date for when the murder occured based on his videos and social media posts, in between the occasional bits of dark humor.
It seems that many of his livestreams were done inside the house, with the room looking somewhat like a basement, so there's the possibility that he was recording himself while in the room with the victim's corpse, though it's not visible in any of the videos.
Sorry to write so much in one post. If anything comes up, I'll post more info, but that's all I know of at the moment that isn't just speculation.
