John Winchester is the husband of Mary Winchester and the father of Dean and Sam Winchester. 22 years ago when Sam was only six months old, he watched his wife burn to death on the ceiling of his youngest sons nursery.

John raised his sons the only way he knew how: like soldiers. He taught them all about the supernatural evil that lived in the darkest corners of the world... and he taught them how to kill it.

Dean, being four years older than his younger brother was often left alone to watch over Sam while their dad went on "hunting trips".
Sam on the other hand, hated the life their father had created for them and had frequent fall-outs with him, very different from the way his older brother treated the man, and as soon as he was old enough, Sam left for law school and met his beautiful girlfriend Jessica Moore. John continued hunting, bringing Dean along when he was old enough.
