The chilling final words of a missing nuclear official have been revealed as the search for him and several others possessing classified secrets drags on.Police in New Mexico said Steven Garcia, 49, vanished without a trace on August 28, 2025, the day before his birthday, after a heartbreaking argument with his wife, Valerie. In April, an anonymous source told the Daily Mail that Garcia was a government contractor working for the Kansas City National Security Campus (KCNSC), a major facility in Albuquerque that plays a key role in America's national defense.That source feared Garcia's case may be connected to the ongoing FBI investigation into the string of missing or dead scientists, nuclear lab workers and former military officials who all had ties to sensitive national security sites and classified data.Now, police reports obtained by the Daily Mail have revealed new details about his disappearance, stating that Garcia's wife announced her intention to leave him due to ongoing problems in their marriage, adding that she did not want to work with her husband on fixing their relationship. The Albuquerque Police Department revealed: 'Valerie said that Steven was upset and told her "well if I can't have you I will go somewhere else."'Those were the last words Garcia uttered before security cameras in the couple's home caught the nuclear lab worker taking a handgun and a bottle of water and leaving the residence on foot.Valerie also told police that the gun was registered in her name and that her husband had stolen it when he disappeared. The Daily Mail has reached out to Valerie for comment. Steven Garcia (Pictured) was last seen on August 28, 2025.
