To make matters more complex, if I were to murder someone I would leave me phone at home, maybe leave it playing videos. It would be much less likely that my phone is randomly at the house of someone who was just murdered if I am truly innocent. That alone does not prove me guilty, of course, but it sure doesn’t look good.

Where did you access it from? Was it a university? As far as I’ve learned, ARPAnet wasn’t available in residential settings.
