Letter From Private Investigator

Warning This Section Does Contain Spoilers

This letter from the private investigator now gives us access to the DeviantTracker program that is on the shared desktop. She gives us a login and password to access. We are told to first listen to the 'Dalia' folder which is the audio of the 9-1-1 call Aura made on the night of the murder. She also gives us access to text messages between Sarah and someone with the initial N but these messages are written in code. To see how to solve those messages please visit here.
