That BBC article should have had a content warning. I wish I hadn't seen those gruesome details and felt sickened. They're rather more careless with my sensitivities than they are with selected others.
It's a badly written article and not just because the unnamed author does not know how to spell disdain. The lie of reporting a male criminal to be a woman is blatant and cruel. And it's amplified in a bold heading and link underneath the article:.
"From other local news sites
Woman, 26, GUILTY of murdering Jorge Carreno "

Then we are informed "...and came out to her parents as transgender at 12."
Stick the word 'transgender' on a child or assert that a child can 'come out as', as if it is something that the child is. It's slipperiness with language. What does the writer think the 'trans' in 'transgender' signifies? It not just a free-floating arrangement of letters. How does the BBC justify using the term? There has to be something behind attributing that to a child. But what? I think we should be told because otherwise we might believe it is taking an ideological position and feeding us a line.
