Inside the Criminal Mind with Former FBI Profiler Andrew Bringuel

Serial predators rarely choose locations completely at random. Where they hunt, encounter victims, commit crimes, and dispose of bodies can reflect familiarity, opportunity, transportation routes, victim availability, and the offender's desire to avoid detection. This episode explores geographic profiling and how investigators use patterns across multiple crime scenes to better understand an offender's activity area.

For months, someone was setting fires at occupied homes in Burnaby, British Columbia, leaving investigators with dozens of incidents but no identified suspect. With conventional investigative methods failing to produce a breakthrough, police turned to behavioral and geographic profiling to narrow the search. A map eventually pointed investigators toward a particular area, but the decisive lead came from someone in the community who recognized what investigators were describing. The case demonstrates an important lesson in criminal profiling: a profile rarely solves a crime by itself—it helps detectives decide where, and sometimes at whom, to look more closely.

In 1980s Britain, investigators faced a disturbing series of sexual assaults and murders associated with railway stations across London and southeast England. Instead of asking only who the offender might be, psychological analysis introduced another question: What can the locations, sequence, and behavior of the crimes tell us about how this offender lives? The investigation of John Duffy became an important early demonstration of how behavioral and geographical analysis could support police decision-making without replacing traditional detective work.

In June 1973, seven-year-old Susan Jaeger vanished from her family's tent at a Montana campground, leaving investigators with remarkably little physical evidence and no obvious suspect. The case became an important episode in the FBI's emerging use of behavioral analysis, associated with early Behavioral Science Unit figures Howard Teten and Patrick Mullany. This episode asks a deceptively difficult question: What can behavior tell investigators when the crime scene tells them almost nothing?

Between 2014 and 2024 a masked man hunted women in a tight pocket of Tucker, Georgia—first in a garage on Christmas Eve, then at an apartment a mile away, then in a bound drive from machine to machine. The attacks sat in separate files until a July homicide arrest put a name on the DNA. The geography never wandered. The face never appeared. That combination is the whole case.

You do not apply to the Behavioral Analysis Unit out of college. You become an FBI special agent, survive Quantico, work real cases for years, then compete for a small desk at NCAVC. The steps are public. The odds are not. Television skipped the decade in the middle.

Long before behavioral profiling was a fixture of crime fiction, two FBI agents began slipping tape recorders into maximum-security interview rooms to study violent repeat offenders. By listening closely to the recurring fantasies and rituals behind unsolved horrors, they mapped out how violence begins long before a physical crime takes place. Here is how John Douglas and Robert Ressler helped build modern behavioral analysis—and where popular dramatizations like Mindhunter meet gritty reality.

Jana Monroe was the first female FBI agent in the Behavioral Science Unit and consulted on roughly 850 homicides, including work connected to Jeffrey Dahmer and the Rogers family murders. In Hearts of Darkness and recent interviews, she describes profiling as crime-scene analysis and victimology used to shrink a suspect pool—not as psychic access to a killer's inner life. That distinction still matters, because television trained the public to expect the wrong kind of certainty.

On April 8, 2026, Rex Heuermann pleaded guilty to strangling eight women whose remains were tied to the Gilgo Beach investigation and admitted an eighth killing he had not even been charged with. As part of the deal he agreed to sit with the FBI's Behavioral Analysis Unit. That is a rare ending for a serial case, and it is also a trap if you treat the interview as the explanation.

a look at vigilantism, Carlos and retired FBI profiler Andrew Bringuel dig into what actually motivates someone to bypass the justice system and act on their own. Using the PEPS model — personal, economic, power/political, and social motives — they break down real cases, including the Bernhard Goetz shooting, to separate the myth of the vigilante from the psychology behind it. The conversation also turns practical, weighing what "good" versus destructive vigilante behavior looks like when communities feel the system has failed them.
