His isolated life on the road provided the perfect scenario for a fledgling killer. His wife left him, and he got injured during police training, disabling him from fulfilling his dream of becoming A Royal Canadian Mounted Police Officer. He was married and gainfully employed as a truck driver. By 20, his seemingly normal life was back on track.

He took out his pent-up rage on innocent animals and other boys, and was also known to start fires. He was neglected by his father, and ostracized by his peers, meaning he lived much of his young life alone.

Keith Jesperson grew up in British Columbia.
