Very odd that they never left any description of the "creepy man" or his vehicle, nor his plate numbers, while they were saying to a friend that they're outright afraid to get killed by their camping neighbor.
As was published a while ago:
Details released in deaths of newlywed couple at campsite
“Investigators were informed that Kylen had mentioned to her friends that if something happened to them, that they were murdered. Kylen had continued by saying there was a “creepy man” around their camp and they had been intimidated by him,” the search warrant states.
It seems there was a slowly escalating conflict around that campsite. To me seems very likely the creep showed up to enjoy camping by the creek with some shade trees by it, which might have been his favorite spot, and got riled up finding he has to share the space and with lesbians hated by him. If he arrived and found some guys, or a traditional family with kids - he most likely would have just left and looked for another spot, as he would be too afraid to enter a confrontation. If he found, say, an older conventional-looking lady - he probably would have setup nearby hoping she'd be uncomfortable and leave the spot for him to have to himself - but he likely wouldn't try to openly escalate the conflict, being afraid of cops /rangers being called on him.
I have to say that seeing alternative looking/dreadlocked women might have made him believe they'd be less likely to call LE on him, as deadlocked people are often perceived as being involved with drugs. As he saw female gay couple, it had probably fueled his rage much beyond just being territorial, and he setup right next and started escalating, harassing them. Until he finally completely lost it over something - may be they decided to push back or him getting very drunk that day. It seems like they didn't believe he was really capable of anything and was all talk, until the last moment - as not only they haven't relocated or shared his description, they actually went to town leaving stuff like the tent unattended (while he could have slashed their tent or steal their stuff).
It's not unheard of for people to go into rage over camping spaces. Just last year, there a local in Wyoming became enraged finding a group of out-of-staters in his favorite campsite (and that was inside a free Tin Cup campground) - he was drunk and proceeded to yell at them, then, as things had escalated, had threatened them with a gun - and got shot dead. One of the camping group was a police chief from Idaho and he shot the guy in self-defense. Even though there was a bunch of up to 18 "tough" guys who rode ATVs all the way from Idaho in that campsite - that one guy became enraged enough at out-fo-staters taking "his" space to try to run all of them off. One trigger point was hate at out-of-state people whom he called "Californians" (even though they were from ID), in this case. Some people can get very territorial over what they consider their favorite spaces on public lands.
