Up to you as both options seem viable. In order to make it more realistic, the latter option would probably work better.

I believe that dealing with a bit more of realism would be interesting. Unless the characters have previously pooled their findings, having them be lost, if a PC quits would make the most sense.

That said, it's really up to you to make the choice.

Hmm ok thanks for the input! Perhaps, then, in the case of PCs dropping I'll give you an alternative way of finding out any info they might have had to themselves. However, I'll also try to have there be several different ways to arrive at the final conclusion, so you may not need all the info to find the culprit.
