This is so tragic, but as others have said, the only culprit here was the rapist. No one else is responsible for the actions of that reprehensible individual.

That said, there's something to be said for general everyday compassion. I would like to think that in times when someone is so close to the fare and there are no more busses coming for hours, that a bus driver could make an announcement over the intercom explaining the situation and see if anyone had the money to spare?

I know I see people jumping on and off the bus all the time. I just figure they're asking if it is the correct bus or not. But if the driver announced a situation like the above, I'd be out of my seat in a second to help, and I think a lot of others would too. I'd hate for anyone to be stuck 15 miles from home, scared and alone.
