Treated like an outcast by his own family and teased by other children for his large size at a young age, Jesperson was a lonely child who showed a propensity for torturing and killing animals. In his younger years, Jesperson was given less attention than his siblings and treated differently by the rest of his family. After moving to Selah, Washington, Jesperson had trouble fitting in and making friends because of his large size. His brothers did not help him, instead they nicknamed him "Igor" or "Ig", a name that stuck throughout his school years. Because of this, he was a shy child, content to play by himself much of the time. He would often get into trouble for behaving badly, sometimes violently, and would be severely punished by his father. This included beatings (sometimes with a belt in front of others) and, in one case, he received an electric shock from his father.
