Former FBI profiler Candice DeLong, who previously worked as a nurse and then spent about two decades investigating crime, describes patterns she observed during interviews with dozens of killers. Across the reporting, the focus is on how different offenders respond after a first homicide. DeLong says some killers stop after one murder, while others continue committing additional crimes. The outlets summarize her explanation that the “most dangerous” offenders share behavioral and psychological traits that keep them engaged in escalating or repeated violence. While the sources provided are limited in detail beyond her background and her central claim about why reoffending occurs, they consistently present her as an experienced profiler whose insights come from extensive investigative work and direct interviews. The articles frame her comments as an attempt to clarify common factors that distinguish one-time killers from those who persist, rather than as a description of a single case or a specific suspect. The reporting emphasizes her perspective as an investigator and profiler rather than courtroom testimony or new charges in an active investigation.
