The main locations in this case are rather far apart, and so I am trying to understand what all might have happened and how they solved this case within a weekend.
Multiple news articles say the suspect is a resident of Hawthorne, an area down in the Los Angeles metro near LAX. She and her sister and sons, and her parents nearby, lived an hour north in Simi Valley area near Thousand Oaks.
So exchanging the boys for the weekend is not popping across town for a few minutes to drop them off or pick them up. With likely traffic, it’s a 3 hour round-trip between Hawthorne and Simi Valley.
Then Victorville, where the suspect was arrested at his parent’s house, is nearly 2 hours from Simi Valley. Through a significant mountainous region into the arid Central Valley.
So, in my opinion, all of these distances make it very unlikely that the ex exchanged the kids somewhere, dropped them off, and then popped back to fight with or kill Rachel. Not when there is three and four hour round trips involved, and he would have to leave his children somewhere for half the day. Everything had to happen between Thursday mid morning and Thursday evening.
I’m still not clear if she dropped off the kids in Hawthorne, or if they met somewhere halfway to exchange, or if he came to her place in Simi Valley to pick them up.
But regardless he ended up at her place, hopefully with the kids in the car versus in the house, and fought with her. The murder seems spontaneous and unplanned, because it is a huge mess with tons of evidence that was very easily solved.
Speculating, Likely they got into an argument, whether about the divorce or the child support or maybe the kids told him something that their mother had said that he didn’t like. So they fight, and he is enraged, and he is physically attacking her escalating all the way to killing her with blood everywhere.
Then he washed all the blood off himself and threw her in the back of his vehicle with kids in their car seats and drive towards Victorville?! Horrific
Antelope Valley, where he dumped her, is an hour and a half from Simi Valley along the two hour route to Victorville. If it was all unplanned, and carried out on Thursday on the drive to Victorville, then he likely had his phone on him. If that is how the body was located in a “very remote location” within days.
