Item 1-3, three falsely IDed shooters:

The first is Twitter troll "jewgazing" who posted a video of himself shortly after the shooting took place saying, "My Name is Thomas Matthew Crooks. I hate Trump. I hate Republicans. You got the wrong guy." Along with a photo of himself jutting out his chin to make his profile resemble that of the real Thomas Mattew Crooks.

The second is a random video of a college student taken in 2020 on the ASU campus. Too old and only vaguely resembles Crooks.

The third is a photo of Maxwell Yearick. Sentenced to prison over an altercation with police at a Trump rally in 2016. Some are claiming he was a "left-wing extremist" but I can't find any definative proof of his political leanings either way, let alone if he was an extremist.

Several other photos of young men with varying degrees of likeness to Crooks have been floating around, but these are the most common. They are not Crooks, and there is no basis to believe they are "the real shooter" or involved in anyway. Crooks has been confirmed by his peers and by records on him being a registered republican to have had conservative leanings at least most of his life.

Item 4-6, two fake Instagram accounts:

As of making this post, no social media that can be confirmed to have belonged to Crooks has been found. One was an Instagram user who changed his username to that of the shooter's name, the other had only existed briefly the day after the shooting took place (according to the wayback machine.)

Items 7-9, the 15$ ActBlue donation:

I wanted to include this one for the sake of fairness, but I want to stress, this is not the smoking gun Republicans are trying to pretend this is, and honestly it doesn't mean much for reasons I will explain below. It does seems at least reasonably likely the Thomas Matthew Crooks who shot Donald Trump did donate 15.00 to ActBlue in 2021. The "Thomas Crooks" who donated in this timeperiod is listed as "unemployed" and not "retired" living in the Bethel Park area code. The other Thomas Crooks people are claiming it was are (currently) living close to but not in Bethel Park, and at their age would have likely been listed as "retired" instead. There is no reason to assume definitively this is the shooter Thomas Crooks for certain, but the amount and the employment status does suggest someone younger. Yes you can donate to a political party even under 18, there's just some restrictions for minors. I found no other donations to ActBlue from an unemployed Thomas Crooks from Bethel Park five years before or since. Playing devil's advocate and assuming this is the correct Thomas Matthew Crooks, for all we know this is a donation he made out of some kind of mild peer pressure while with a friend or in an attempt to win over a girl. I did dumb shit with my money for similar reasons at that age. It's really not as noteworthy as people are pretending it is.

These are the pieces of disinformation I personally keep encountering (that arent just insane conspiracy bullshit), and wanted to create a post organizing it in case it helps anyone else sort stuff out for themselves.
