Although I voted that he committed murder, the irony of finding this thread while I took a break from studying for my Criminal Law final is too much. Honestly, there is an argument that he may have committed voluntary manslaughter, which isn't technically murder, although it is homicide. Under the Model Penal Code (which is sort of a legal guideline for legislatures that a bunch of Crim Law professors dreamt up, and isn't really a binding authority at all), if someone commits homicide while suffering from "extreme emotional distress", it would be considered manslaughter. Given the state of his personal life, it's actually pretty feasible that an argument could be made for this. But to make a long story short, he still killed her.
