Editing Shawn Nelson (section)

===Prior to the rampage===
Nelson was born in Birdseye, Utah, on August 21, 1959.

Nelson was hospitalized in 1990 for neck and back injuries from a motorcycle accident. He sued the hospital for $1.6 million, citing negligence, assault, battery, and false imprisonment. A superior court judge dismissed the case, and the hospital counter-sued for $6,640 in medical fees and legal expenses. Nelson claimed that he was forced to be treated without his consent.

His wife of six years filed for divorce against him in 1991, and both of his parents died of cancer in 1992. Scott Nelson, Shawn's brother, said that Shawn became addicted to methamphetamine in the few years prior to the tank incident. His neighbors complained to authorities of Shawn yelling at his roommate at night. Nelson then began to exhibit unusual behavior. On one occasion, he dug a hole 15 feet (4.6 m) deep in his backyard in an attempt to mine for gold.

In February 1995, he filed a notice informing the county of his plans to mine bedrock in his backyard. Nelson's fishing friend, Carson Honings, referred to the mine shaft as Shawn's "new hobby". In April, he filed two damage claims against the city totaling $2,000,000. One of them was for police negligence, and another for false arrest.

Nelson's neck and back problems, combined with the theft of plumbing equipment from his truck, effectively halted his business. With no income, his utilities were cut off and his house was in foreclosure. In April 1995, his live-in girlfriend died of a drug overdose. His brother, Scott, said of him, "My brother was a good man. He'd help anybody. He just couldn't help himself."
