Like Manson Family doing their 'creepy-crawlings' stuff in numerous homes before August '69. I'm thinking the same, actually. Each time I hear/read 'it's thought the perp may have been inside before 11/12' my mind immediately questions that with 'was he in there knowingly to the tenants, or unknowingly?'
I want to relentlessly compare this case to the Tate-LaBianca case, as well as the Holly Bobo case. Why?! IDK. Understandbly each case is different and are case-by-case scenarios. I get that. Constant variables and such. But, those are the main two I go to when comparing, for some reason.
Having said all that, it leads me to two more points.
1) Karen Bobo is the gold-standard when it comes to a grieving parent going before media, imo. Press conference after press conference and saying what she had to say/was able to say without revealing what LE didn't want her to say and not answering too many q's from the press or public.
2) The perp's name has crossed the desk of LE at some point prior to 11/12/22, imo. Fights with family members/domestic assaults, car theft/theft of property, public nuisance, drunk and disorderly, poss of meth (hard for me to believe perp wasn't amped up by something on 11/12/22), endlesss possibilities. But, my point is, his name has likely crossed a desk prior to 11/12/22. Zach Adams' name had, Jason Autry's name had, Shane Austin's name had, and countless names of Manson Family Members had. So, imo, this perp's name has been in the mix somewhere prior to that night, maybe in different jurisdictions, but it's there somewhere.
All just my opinion and pure speculation.
