Resentment toward his baby brother
The child apparently struggled with feelings of desertion and developed anger toward his younger brother by the time he entered school at age six. Teachers characterized him as shy and reserved, frequently feeling neglected because his mother struggled with depression and hypochondria, and his father was away studying.
The home was tense. His parents were often at odds, and his mother, who required daily care and was confined to bed most of the time, even tried suicide at least once. Later, the youngster acknowledged that he never felt secure in his family and was uncertain about the survival of his household.
But as a child, the slender, blond lad did have some friends.
“He was a fun kid to be around as a child,” said Ted Lee, who grew up in the same neighborhood.

However, as the young man grew, a sinister obsession surfaced. According to others, it began when he was four years old and observed his father unearthing animal bones beneath their home.
