A few months ago Andy Ngo did a twitter thread on the black trans women that were killed, I am not sure how comprehensive it was, but they were involved with prostitution and drug addicts.

So, black transwomen being shunted disproportionately to this shitty lifestyle
is the root cause.
Transwomen probably have shittier jobs, more easily fired, and have less desirable and stable guys willing to date them. FInally, guys who have sex with them must be a bit paranoid about it being known - especially guys in the crappy lower unstable segment of society.
But they are not being hunted down by strangers.
