Thanks to my wife, Elise, for her immense help and understanding; my assistant, Jean Hamilton, for retrieving and organizing information for both the writing and the vetting of this book; Mike Campbell, my editor at Skyhorse, and my agent, Linda Langton. Without Richard Ciccone, MD, I might never have received the case referral. Steve Zansberg provided valuable legal counsel. Claudia and David Ladensohn, Terry Ganey, Bob Kolker, Judith Bass, A. D. Oppenheim, and John Mayer helped to get things off the ground and keep them aloft. Appreciation also goes to my former assistant, Kathy Pomeroy, for her work in the case itself, and to federal, Colorado, Arapahoe County, and Aurora law enforcement; Colorado Assistant Attorney General Tanya E. Wheeler; Colorado Mental Health Institute-Pueblo personnel; and Arapahoe County corrections staff. Many readers reviewed and criticized early drafts and chapters: Aileen, Alan, Brandi, Buddy, Dan, Doug, Elise, Jan, Jana, Jodi, Jon, Kyle, Michelle, Mollie, Ron, Skip, and probably more. My brother Dan Reid of Paladin Precision Shooting, LLC (see his recent book, Guns Are Stupid, People Are Smart) and former FBI SWAT and firearms instructor Joe Holtslag provided valuable information on weapons and tactics. Apologies to the kind folks that I’ve inadvertently omitted.
