Did we ever get an answer for this [@StormWolf]? I just posted in the IC thread but I kept it super vague because I didn't know what had been decided.

not inventing clues so much as go about your characters' process(es) and have them investigate an area as broadly, narrowly or esoterically as you think fits. If they are looking for something in particular, express that in a narrative manner. 

If this was a game of Delta Green, for example, this is a round of "Spot hidden". Alternatively, Chief Millar is available for questioning/grilling.
