Wow, what a sad story!
Here are my thoughts (in no particular order):
1. As a health professional I don't know how anyone can confuse a head wound with an "upper torso" wound. Unless they just glance at where most of the blood is (ie, it ran down onto his shirt) but don't bother to look for the actual wound(s). The reporting/giving of information on this case has not been great, to put it nicely.
2. My best guess is that Tristan was awake, sitting up, and using his phone or iPad/tablet to check whatever, or maybe send his wife a text message to wish her luck on her exam. I think the screen light from the device attracted the shooter to the tent, and maybe created a shadow that became an easy to hit target. However, we still don't know if Tristan was shot from outside the tent, or if the shooter (or just his gun barrel) entered the front of the tent. If the shooter entered there should be footprints. I don't think he entered the tent.
3. I don't think Tristan was targeted. I think his shooting is related to the previous shootings. I think it would be an odd setting for a hit, and a hit man or jealous and angry professional likely would have used a silencer to avoid attention.
4. I'm thinking the shooter is a young male who perhaps only started shooting back in 2016 (?). His aim was off then, and during the three shootings prior to Tristan. When he shot at Meliss Tatangelo he hit the car but missed her and her boyfriend, etc.
5. The timing of most of the shootings appears to be during school (college, maybe boarding school) breaks. We don't know exactly when in January 2017 Meliss Tatangelo's shooting occurred but it could have been during winter break. The shooting that doesn't fit is the one with birdshot in 11/2016. But that could have been before the shooter ? started college or boarding school.
6. I'm assuming maybe a different gun was used for each of the shootings where LE recovered a bullet prior to Tristan's shooting (?). Unless of course no one bothered to see if any of the bullets came from the same gun...... (Tristan died from at least 1 gunshot to the upper torso, oh no wait he died from a gunshot to the head, oops we forgot to check where all that blood on his shirt was coming from, yeah we applied pressure to the wound, oh wait that wasn't a wound...). IF the bullets came from different guns then maybe dad or grandpa has a gun collection? We'll have to wait to find out if Mo, Curly, and Larry really ever checked for a gun match. Of course if one or more of the shootings is under the jurisdiction of Abbott and Costello, then it becomes more complicated.
