Patrick Purdy Official Report [99 pp, 3.2 Mb]

This document is actually several documents on the case, including a chronology of Patrick Purdy's life, his contacts with the mental health system and the legal system, a psychological analysis, his preparation for the attack and details of the attack itself, and his autopsy. This is the best source of information on Purdy that I have found.
