As it turns out, the only male killed by what police think is a serial killer was wearing women’s clothes when he died 5-10 years ago and he was quite possibly a sex worker. He was in his young 20s, about 5’6″, and had one of his top teeth missing.
The police are still looking for leads in this case, so if he looks familiar to you in any way, please do contact them, and do forward this link to those in the NYC and LI area, especially anyone you know who was active in any gender community at the time. We certainly don’t know how this person identified, and there are no details about any body modifications or the like, but it’s likely he was some flavor of trans and that someone knew this person in one gender or another.
