Before beginning his career as an author of true crime books, Don Davis worked for 30 years as a UPI correspondent on various assignments, including the Vietnam War and the White House beat. His works since have covered major crimes of the 1990s. They include Bad Blood: The Shocking True Story Behind the Menendez Killings (1994) and The Milwaukee Murders: Nightmare in Apartment 213: The True Story (1991) about the Jeffrey Dahmer case. Davis's other works include his first novel, Appointment With the Squire (1997), about World War II, and another novel, The Gris-Gris Man (1997), a story about voodoo killings in New Orleans. In addition to being a writer and reporter, Davis was an instructor of journalism at Boston University in 1979, and a lecturer at the U.S. Navel War College in 1983.

Eugene Patronis is Professor of Physics Emeritus at the Georgia Institute of Technology in Atlanta, Georgia, USA. He has also served as an industrial and governmental consultant in the fields of acoustics and electronics.

Pat Brown is a nationally known criminal profiler, television commentator, author, and founder and CEO of The Sexual Homicide Exchange and The Pat Brown Criminal Profiling Agency. She has provided crime commentary and profiling and forensic analysis in more than 2,000 television and radio appearances in the United States and across the globe. She can be seen regularly on the cable television news programs on CNN, MSNBC, and FOX, and is a frequent guest of "The Today Show", the "CBS Early Show", "Larry King", "Inside Edition", "Nancy Grace", "Issues with Jane Velez-Mitchell", "Dr. Drew", "Joy Behar", and "America's Most Wanted". Her radio show "Profile This!" airs every Sunday on BlogTalkRadio (9:00 pm EST).For four seasons, Brown profiled crimes on the weekly Court TV crime show, "I, Detective". She is the host of the 2004 Discovery Channel documentary, "The Mysterious Death of Cleopatra." In the spring of 2006, Brown went inside one of Florida's maximum-security prisons to interview a child murderer for the Discovery Channel series Evil Minds"." In 2010 she profiled a new Jack the Ripper suspect for Investigation Discovery's "Mystery Files." She is the author of "The Profiler: My Life Hunting Serial Killers, " "Psychopaths, " and "Killing for Sport: Inside the Minds of Serial Killers", and is a contract writer for Crime Library. Brown contributed special feature content included in the 2005 home DVD edition of "Profiler: Season Two" and the 15th Anniversary Edition, 2006 DVD release of Quentin Tarantino's crime classic "Reservoir Dogs".Since 1996, Brown's organization The Sexual Homicide Exchange (SHE) has offered criminal profiling services at no charge to law enforcement and training for detectives. Its latest program, "All Our Children Matter", is dedicated to stopping violence against children through criminal profiling education and proactive training for parents and communities.
