This fall marks the 30th anniversary of one of the most terrifying times in Nebraska's history: The year that a young Air Force Airman went on a killing spree, leaving two young boys dead and a community gripped by fear. Now, dramatic and chilling new evidence comes to light exposing the sinister thoughts running through the mind of John Joubert--the man behind the Nebraska killings. Former TV news anchorman, investigative reporter and three time Emmy winner Mark Pettit returns to the case to write the final chapter in his best-selling, and now newly updated book: A Need to Kill: The True-Crime Account of John Joubert, Nebraska's Most Notorious Serial Child Killer. In the spirit of Truman Capote's "In Cold Blood," Pettit delves into the Joubert case to tell the dramatic story from all angles as a non-fiction novel. In a series of exclusive, face-to-face interviews with Pettit, Joubert admits to a string of violent crimes and another killing that sends investigators into a frenzy ending with Joubert being convicted for a third murder and ultimately executed in Nebraska's electric chair. Now, 30 years after the murders in Nebraska, Pettit uncovers shocking new evidence from Joubert's prison records that proves the killer was fantasizing about committing more violent crimes. Never-before-seen death row drawings made by Joubert while he waited to be executed once again send a chill through Nebraska and those touched by Joubert's horrific crimes. In the updated version of his book, Pettit opens his investigative files to the public and for the first time, shares handwritten letters Joubert wrote to the journalist while in prison. Pettit also reveals aspects of Joubert's personality gleaned during the exclusive interviews and details from the death row discussions that have never been shared publicly.
