If you look up the mom's facebook you can see this was a military family which explains how he learned how to shoot.
What isn't explainable is how these shooters keep having these written on the bullets, just like the IDF does with their bombs.
I believe this is the shooter, but don't believe the official story this was some sort of lone nutjob. They even referenced a Discord chat but dismissed it.
Of course Patel fingered his own ass like he was the one who caught him when in fact he was turned in by family. These people are such scum.
