It would be nice to be able to make questions related to found evidences.
For example, I saw from the phone router that the 804 called the victim at 19.15 and the murder has been estimated between 19.00 and 20.45 (ish)
So, selecting this specific evidence, I would be able to ask 804 more information about the reason of the call.
This is just an example, but the idea is using evidences to be able to make more specific questions.
Yes, I know this is not an easy feature because the graph of related questions could be huge, but this could improve a lot the interview side of the investigation, that is very important
So it would be good to keep in mind for the near future
