You seem to be putting forward two motives - a spat because of an insult thown out by Jodi and a goth hate crime. Jodi was 14 - I don’t believe she had any tattoos (though her boyfriend had an illegal one). mMurdered women quite often have their clothes removed or hair pulled out if there was a struggle, even ones that aren’t Goths. What goth make up was Jodi wearing that night?
I said it is possible the perp called out some derogatory term aimed at J J due to identifying as a goth with her responding in kind and the whole thing escalated. Either way I think its possible the murder was effectively a hate crime due to identifying as a goth.
We do not have the full facts from the pathologist re tattoos, permanent and semi-perm, piercings, nail varnish, make up, jewellery, clothes and any other attire and adornments.
Clothes are usually removed where the crime involves a sexual element.
The jury heard one explanation for the mutilation and that involved L M reenacting the Black Dahlia murder despite the fact J J's injuries are incompatible with this. The jury did not get to hear the fact J J may have been the victim of a hate crime due to identifying as a goth.
