You where a child at Sheppard's Orphanage and where adopted at least a year before the horrible tragedy struck where all but three of the children where murdered. You left only months before.
After being adopted from Silent Hill he went to live with the quite wealthy Brown family who gave him a good education at well thought-of schools, finally finishing with a degree in psychology. Setting up practice first in Los Angeles he made a nice life for himself, marrying his highschool girlfriend and having two children together, a son and a daughter. But then the dreams started, first he wrote it off to simple stress from setting up practice and building a life and he started taking sleeping pills to get a proper night's sleep. But they wouldn't go away... and the pills became a need to just go to sleep at night, a fact he hid well from the outside world and even his family. He withdrew emotionally more and more, alienating himself in the process of years from his wife and kids until finally she had enough and left him, the children choosing to go with their mother. In the end, he decided he suffered from a form of survivors guilt for having left shortly before the murders and he needed to go back to Silent Hill to deal with his past. Under the pretence of setting up a practice in town to help there with the still existing problems he moves back to the town where he was young...
