As to whether Hitchbot's fate was sealed because it ventured through a high crime area (article doesn't say specifically where in Philadelphia) -- I imagine such neighborhoods may also have highly suspicious attitudes towards automatons with cameras.

tl;dr Hitchbot was found dismembered in what sounds like a touristy, bar-filled area of Philadelphia. Someone claimed to have footage of it being dismembered, but it turned out it was just a prankster who faked the footage to capitalize on the attention. So it's not even certain where or when Hitchbot "died". But Hitchbot is not really a "bot" as we (or at least I) think about them these days, e.g. the "suicidal" security bot in D.C. that stumbled its way into a fountain [0]. Hitchbot was entirely dependent on people picking it up and dropping it off. The chances of someone choosing to drive late at night to an area of high violent crime seem low in general, nevermind to drop off a robot there.
Ironically I think its chances of survival would be just as good in inner city Philadelphia as it would be near any sports bar in America (or the world), late at night.
