"Without solid connections between homicides, we may have the reverse problem of believing three local murders are the work of one serial killer when they may actually be the work of three!"
About this Quote
Pat Brown warns against a seductive narrative trap: the urge to impose a single pattern on separate crimes without hard evidence. Serial killer stories captivate the public and the press, but investigative rigor demands more than a dramatic through-line. Solid connections mean verifiable linkages such as DNA, ballistics, distinctive signature behaviors, timeline compatibility, and credible geographic patterns. Without them, an apparent cluster can be a mirage born of coincidence and our brains tendency to see patterns where none exist.
The point balances a companion risk. Investigators can fail to connect related homicides and miss a serial offender. The reverse error is just as dangerous: over-connecting unrelated murders and chasing a phantom. Both mistakes spring from cognitive biases like the clustering illusion and confirmation bias, compounded by the media incentive to craft a single, gripping story. When agencies assume one offender where there are several, resources get funneled toward a unifying suspect profile that may fit nobody, evidence that does not conform gets discounted, and families wait while the actual perpetrators remain free.
Brown, a profiler known for challenging popular myths about serial crime, emphasizes the difference between modus operandi and signature. MO can change with circumstance and learning; signature reflects the offenders psychological needs and is more stable. Yet even signatures can be mimicked or misread. That is why corroborating forensics and careful case linkage analysis are essential. History offers reminders: debates over which murders belong to Jack the Ripper, or contested attempts to group disparate deaths under theories like the Smiley Face Killer, show how easy it is to construct a pattern and how hard it is to prove one.
Prudence does not dull urgency; it sharpens it. Treat each homicide on its own evidentiary merits, test linkages against disconfirming facts, and let the pattern emerge from the data rather than from expectation. Lives and justice depend on that restraint.
