 In mid @-@ 1969 , Kaczynski moved into his parents ' small residence in Lombard , Illinois . Two years later , he moved into a remote cabin he built himself just outside Lincoln , Montana , where he lived a simple life on very little money , without electricity or running water . Kaczynski worked odd jobs and received financial support from his family , which he used to purchase his land and , without their knowledge , would later use to fund his bombing campaign . In 1978 , he worked briefly with his father and brother at a foam rubber factory , where he was fired by his brother , David , for harassing a female supervisor he had previously dated and who had refused him as a boyfriend for not " sharing much in common .
