This is an error. I just spent half my morning trying to track down the source of the word "dismemberment."
The police said "the body was not intact" according to reliable news sources, such as the L.A. Times. They also said she was in an advanced state of decomposition. Disarticulation of a body during decompensation is normal and expected. It does speak to the amount of time she was in that car (11 days just at the car lot?)
No where do the police mention dismemberment, but some reporters and many TikTokers took "not intact" phrase and made it into "dismembered." Then the word grew legs and many began to use this highly sensationalized version.
IMO, no police report would mention dismemberment until a medical examiner had produce evidence from the bones (which there would be). There would be cut marks on the bones if the body was disarticulated by another human wielding some kind of tool.
So, that is not an indication of criminal intent (yet). We have to wait for the autopsy report which, I predict, will remain under seal until there's a trial in this case.
Anyway, other journalists/bloggers/tiktokers/youtubers have considered the idea that she died elsewhere and then was stuck in the trunk (a criminal act, but not a homicide).
We're going to have to be patient here, I think.
