I've figured out the motive
guy was desperate for a wank, didn't have a sock to do it into. Asked the girl for a lend of her sock. She said no, he killed her, wanked into her sock then ate her pizza.

Yeah.
I mean, most men would have taken a clean sock from the drawer for their wank, not take a used one.
