I suspect that one of the reasons there has been so much confusion regarding name/sex/gender is that this person was either extremely new to social transition or was only using a male name online.
All the professionals, family, friends and neighbours interviewed so far have used the person’s birth name.
This doesn’t mean anything re: hormones though - lots of trans people in the US seem to take cross sex hormones for quite a while before changing name/updating paperwork etc.
Oh, and in case anyone is wondering why my mass shooter stats upthread are much lower than the massive ‘there have already been X mass shooting THIS YEAR’ numbers, it’s because some databases don’t discern between types of mass shootings, and include things like gang related multiple murders and family annihilation crimes.
All murders are a tragedy and bereavement via murder is hellish for loved ones left behind (some of you will remember that my family lost someone to a random wrong place, wrong time murder) so when I’ve been trying to parse the data it’s purely on the basis of specific offence type.
Thankfully, this type of crime, the mass shooting of strangers in a public place, is the least common type of mass shooting, although it is the type that gets the most press attention.
