I'd almost forgotten about the US Marshals, Wildhorse! You're right, we never have received an explanation why they were brought in.
I second you in wondering if OtherHand can tell us more.
One thing I've wondered is if examining the map of the search flights shows whether planes flew over their final location, and if so, when. If the planes did fly over their final location on a particular day (for example, the first Saturday), then we know they were dead before then, since if they were alive, they'd presumably try to signal--or at least not commit suicide. Who would commit suicide when planes were flying around overhead searching for you?
I'm inclined to think they were both dead well before the search began. Why, is a whole other question. I don't buy the 'Mercy Killing' theory in any way, but it's possible that the authorities will latch onto it, because I don't think the legal profession has a term to describe what happened, and they need to find an official explanation and close the case. If it wasn't a planned homicide, or reckless homicide, what was this event?
Just my opinion, of course, but: I definitely don't think it was a consciously planned murder. Rather, I think it was a combination of drug use combined with Orbeso's pre-existing anger or depression that combined into a fatal perfect (sand)storm of disaster. The gun was brought along very much in the way that Chekhov's Gun theory works in stories: once he put it in his backpack, it was inevitable it was going to go off.
But leaving aside Orbeso's psychological issues or dark unconscious motivations, whatever they may or may not have been, there's the drugs. I think they were key to the calamity. I don't know if toxicology tests will be able to find drugs in their bodies anymore, or if they were carrying any drugs on their persons. But even without physical evidence, there's the other facts: the 4 hallucinogens found in the AirBnB, the widespread use of drugs while hiking at JTNP (it's so commonplace and revered a rite in drug culture that there's actually a name for it--it's called The Joshua Tree), that their social media was loaded with a lot of drug references--and last but not least, the first basic fact that they got so badly lost, on a marked trail that thousands of people have previously traversed without losing their way. Why? Probably because they were on a drug or drugs that makes you inattentive and distorts your visual perceptions. Ed, you asked about timing. It may seem odd to us old fogies to think about taking a drug early in the morning, but that's probably what they did--there's numerous references I found online to people taking shrooms with breakfast before starting out to hike or climb around JTNP. If they took shrooms around 7 a.m. the trip would last about six hours or 1pm. By that time, they were likely well and truly lost as well as suffering from heat exhaustion and dehydration. But I don't think we should by any means assume that shrooms are all they took. In fact that's unlikely. Many of the accounts I found online, people had taken multiple heavy duty pharmaceuticals.
https://www.reddit.com/r/Drugs/comments ... _national/ This link was 'mind-blowing' to say the least. It's from a hike in Yosemite, not JTNP, but it gives you an idea. Apparently Yosemite also has an enormous issue with stoned people wandering around.
Here's a link that describes drugging at JTNP , including, alarminly, driving around
https://www.shroomery.org/1836/Joshua-Trip I also recommend looking at sites like bluelight or erowid to get a better idea of this particular kind of drug culture. So they may have been on multiple heavy duty hallucinogens and 'dissassociatives' like ketamine or its derivative chemical cousins (very popular now, apparently.)
I could be totally wrong, of course, and maybe they were stone cold sober, or pretty sober, and just somehow badly missed the trail. But that still doesn't explain why Orbeso was so agitated and despondent in a situation they still had some chance of surviving, he shot his friend and himself. But if you combine one or more fairly heavy duty drugs with heat exhaustion and dehydration to create the mother of all bad trips, plus some pre-existing anger or depression, plus a gun .... well, I can see how that would go very, very wrong.
Maybe I've got it all wrong, who knows. But I just can't find any other logical explanation for these disparate and very strange facts. Anyway that's my 2 cents.
