In this theory, which is not very complicated, I observed the locations of the crimes committed by the infamous Z, in the first two counts of simple letters and the place where Stine (taxi driver) was murdered, I thought, because the registry was an end of trip (Maple with Whashington) and the taxi was more forward ( Cherry withe Whashinton), figured in his sick mind would present some relevant information. Anyway just watch the image below.
