One of the many homeless people in Los Santos who go unnoticed.
Not much is known about John "Connor" Shoemaker, but all that is known is that he has some sort of Mental Disorder, possibly Schizophrenia. He would ramble on about how the Galactic Empire killed his wife for treason and that he can still hear the "Screams", to which he would Scream out loud afterwards.
Mr. Shoemaker was murdered because he stole a Porsche. And only that.
