Is this a rerun of the McNee case? Rentboys thinking they can get away with killing queens because they feared they were going to be raped/have fingers inserted up their straight holes? Nicking their victims' cars seems to be a theme too.
In my book, using the "gay panic defence" should carry a stigma of being considered less than heterosexual (no straight man fears an old queen, surely!), and should add a few years to their sentences.
UPDATE: the little shit was found guilty of murder, as it should be. Hopefully he'll be sentenced to allow access to all areas in prison.
