I had seen the Sierra Halseth case before, but I watched the American Monster version of it yesterday on a break from doing work. This video is not that version, but a similarly good version from Truly Criminal:
The short form of this case is that Daniel Halseth married pretty young. They popped out three kids in about four years. Sierra was the youngest. The couple, and the three kids, moved to Nevada (from Oregon) for his work. They were there a few years and the mom got involved in politics, then became a State Senator. This was a precipitating factor in the parents getting divorced. The dad, Daniel, even did a little jail time for harassing the mom. Eventually the mom took the kids and fled to Alaska, with a new dude, so Daniel moved to Texas and focused on his career.
Right around COVID, the kids and the mom were back in Nevada, and Daniel had to go out there for work and started reconnecting with the kids to the point that he was living in his client’s rental house by now. Sierra, the youngest, probably manipulated him and created an intense custody battle between her parents as she primarily lived with him. She was dating a dude named Aaron, who was 2–3 years older than her and apparently did LSD, and for various reasons that still don’t make sense, they killed Daniel and fled to Salt Lake City, where they were eventually caught on a tram.
The case is probably most famous because the killers made this video showing no remorse and discussing how much sex they were having post-murder:
