Pure speculation. There are no leads at this point.

Wow, you really are ignorant, aren't you?

Okay, first, there should not be a major degree program called "gender studies"; maybe a course in the language arts department.

Second, s/he pretty much appears to be my enemy on all fronts, the least of which was his/her twisted views on sex.

Third, how do they know s/he was killed because of his/her sexual confusion? Maybe a rapist mistook him for a girl, then killed him when he found out. Maybe it was a mugging gone very bad. Maybe s/he was meeting someone for some clandestine purpose, and a gang-banger came along to make his bones...

As Mimi speculated, it was probably a fellow illegal that killed him/her.

Think of it as evolution in action...
