Even after Chester explained it to him, Callum didn't know what to think about the matter. It felt somewhat weird to him. 

The phone call still felt surreal to him. There was no way that someone from his past would have been able to find him that easily.

If they could've, they would've tried to do it much sooner than this. 

Chester couldn't put his finger on what it was, but something was bothering him. 

"I know that no one did anything about it before, I'm trying to change that right now which is why I need you to work with me on this. Without your help, I don't know where to start." The detective tried again. 

The woman looked like she was almost in tears. It was her son that had disappeared after all. Anyone would be distraught over that kind of thing happening. The police in the area obviously hadn't done their job otherwise they would have been able to find the right clues like he had been doing.
