Please remember to check the source. I believe Shoemate has been known to falsify emails in the past. Also, if you check out the screenshot he shared on the podcast, the email has spell check cues highlighted. This means it is in edit mode, not a capture of a real email. As someone else posted, the writing style and subject does not seem to match his previous known writing. There may be good explanations for these discrepancies, but I do not trust most of the reporting to actually dig into sources before posting online to get clicks.
Thanks, it is not your fault. As I said, it may be legit, but I just feel like everyone wants to be first to report something before fact checking. This incident is very strange, and the suspect seems to be all over the map. There was an article yesterday that reported on his very recent communications with his ex girlfriend. Matthew was currently engaged (previous marriage and divorce) and had a young child. Strange that he is communicating with his ex( not his previous wife), the day before he shoots himself. There are other writings that Vegas police have shared that seem to contradict the incident, so we may never know what actually was going on with him.
