In what way is this supposed to be a relevant detail? Unless you think that they are killing people because they are trans, why should you report that they are part of a marginalized group? If they were mostly blondes or had freckles, should that be part of the story too?
It seems as if the group targeted trans member in their recruitment - and then used evidence of general marginalization to justify their crimes.
If you look up old reddit threads about the murder of the landlord, you can see many people defending the crime as the landlord was transphobic. It's not just a random detail like freckles, it seems like the identity shaped the way this group interacted with the world.
It's basically impossible that it's a random irrelevant detail, I'd say any such detail is fair to share.
For example, if every member of this group was Indian American I'd consider that a fair detail to note, the chances of that happening at random are minuscule, yet that's orders of magnitude more probable than all of them being trans for no reason.

No it's not, what? People tend to hang out with people similar to them. Most gangs are racially or ethnically homogenous. That's fairly normal.
In fact, there are commonly Indian-origin gangs in Canada (I haven't heard of it in the US, but the US has much higher-income immigrants from India overall)
