Over the span of roughly a month in the Sacramento winter of 1977–78, Chase carried out a series of killings defined less by victim selection — there was none — than by what followed death. His crimes were driven by a delusional belief system that shaped the nature of each attack, and investigators who worked the cases described the scenes as among the most disturbing they had encountered in long careers. The legal proceedings ultimately affirmed that he understood the nature of his actions, a determination that complicated the popular narrative around his mental state. He remains a subject of study in forensic psychology for what his case revealed about the relationship between untreated psychosis, institutional failure, and violence.
