If we are to believe that Asian Male was picked up by accident, then it is unlikely he made that mistake in this case.
I believe Manorville John Doe was killed at the same time as Jane Doe #6 in early September of 2000.
If she was a working girl then like SG, she had someone waiting in a parked car for her. This time there wasn't any SG screaming to wake up the neighborhood, and thus saving the driver/boyfriend/pimp from entering the house to meet his death, too. MP was lucky to get away because of SG.
This was a 35 year old'ish hispanic male, around 5' 6" and around 130 lbs. His jaw had been wired shut in the early summer of 2000, thus losing close to 20 lbs on a liquid diet. No health issues, no transexuality, no prostitution. Just a driver who LISK had to dispose of, as well.
