I'm suppose to deliever drugs to Don Hostetler at the Crimson Caravan... but I think the family that just died... [Alice shot her mother?]
I'm not sure if they were Hostetlers or not, but what do I do now? All he says is "I should kill you right now for what you've done" [something along those lines]

.. anyone?

It said I failed it when I killed motor-runner, other than that, I've never heard of the quest.
