I'm inclined to believe Nitro and his circle because they were the first to post pretty much anything about it and were actually close w/ the chick
"I'm inclined to believe friends of the mass shooter, they're certainly upstanding individuals. I am very smart."

Some more Wisconsin shooter info, and the third page of her "manifesto."
- Her boyfriend had known her for two years. They were in a long-distance relationship and had never met in person. They met on social media.
- He says she never previously expressed any desire to commit a shooting, and only sent him her manifesto the day of the shooting.
- Timestamps of their messages shown to me demonstrate she sent it to him via WhatsApp at approximately 10:30 am (eastern). She posted it to Twitter at 11:50 am (eastern). The shooting occurred around 11:57 am (eastern).
- He did not see her message until 1:12 pm (eastern), at which point the act had been committed and she was already deceased.
- He describes her as being kind, generous towards him, and cheerful. He describes her as always making him gifts and never expecting anything in return.
On page four of her manifesto, Samantha says that she acquired the weapons to commit the shooting through “lies, manipulation, and my father’s stupidity.” Her boyfriend says he was aware that there was a gun safe in her house, but does not know how she got access to it.
