The document discusses the mind and behaviors of criminals like Mr. Harvey, a serial killer. It describes how he was corrupted from a young age by his mother's influence, which taught him to steal and view women as inferior. As an adult, Mr. Harvey exhibited lying, lack of remorse, planning of killings, and obsession with murdering young girls. The document also draws parallels between the killing of Susie Salmon by Mr. Harvey and the real-life case of 8-year-old Tori Stafford, who was abducted and murdered in 2009.
