By providing empirical data and multidisciplinary considerations, the book increases awareness of child sex offender suicide among the various entities which come into contact with this population of offenders. This book attempts to bring awareness of this potentially high risk population to better inform the law enforcement, corrections, and mental health communities of the unique risk factors for suicide among CSOs and provide a more effective crisis response. The Federal Bureau of Investigation (FBI) Behavioral Analysis Unit III- Crimes Against Children reviewed and analyzed 106 male Child Sex Offenders (CSO) who committed suicide during the course of a child sex crime investigation.  Of the 106 CSOs, 79% were child pornography traders/collectors, 43% were child molesters, 21% were travelers, and 18% were child pornography producers.  Analyses also revealed that nearly all were Caucasian and the majority were married, employed, and died via self-inflicted gunshot wound.  Of particular interest was that in 26% of the cases, the offender killed himself within 48 hours of his awareness of the investigation; and in nearly half of the known cases, the offender had past/current military service and a criminal history.  In addition, 68% left a suicide note, which is substantially higher than the general suicide population. Analysis of the notes revealed common aspects and themes including cognitive distortions, burdensomeness, shame, and self-blame. The most frequently cited reason for the suicide in the note was the child sex crime investigation.    .
