Are you gonna add clues to help solve the unfortunate incident... or a point and click system to examine an area to uncover evidence? Such as crime scene or suspected areas leading up to the incident. Will Rex/MC be able to interrogate/question likely suspects?

There will be hints on who the killer is spread across the story but the protagonist isn't going to have a clue inventory. There might be a point-and-click section somewhere within the game, but nothing like that has been planned thus far. And the protagonist will talk to suspects and see if they're the killer.
