I am not sure where you are in the game - are you in the killer's house? If so, there should be a text document on your phone about Hawker that you have to read before you can call Claire and talk about him - maybe that's what you need to do?
Let us know.

You are now at the climax of the game - so you should have finished - examined - seen - read everything (Karson, Paloma, Fernandez and Hernandez). Check your smartphone, examined all evidence and see.
