A lot of things came together that provided very ideal conditions for serial killers to be able to kill while evading capture. There are also theories on social conditions which came into play that nurtured more serial killers than usual.
Before the 1940’s, America wasn’t very physically interconnected for the average person. Most people didn’t travel frequently, staying in the same general area for years at a time except for special occasions. And the accessibility to travel wasn’t quite there. You could travel to a few states away, but doing so was usually done with plan, effort, and expense that only really lent itself to necessity.
Beginning in the late 1940’s and early 1950’s, however, America made a *huge* investment in automobile infrastructure. Within a few years, you could drive two or three states away in a matter of hours. The average American went from only traveling on special occasions to having huge swathes of the country accessible to them on a whim of they had a car.
Which really brings us to one of the cruxes of the issue. Very rapidly, the suspect pool for a given murder expanded from a small group of people that a local police force likely already knew to a much larger group of people they *don’t know* who could reside *hundreds of miles away*. A serial killer could suddenly travel to do their killing, which greatly negated the ability of police to track them. Local police forces generally didn’t communicate without cause, so there wasn’t necessarily anyone connecting the dots on a group of similar murders spread across several jurisdictions.
Another huge cause was the social conditions. The unfortunate reality of the baby boom is that, following the end of World War II and Korea, a huge number of soldiers were returning from war with severe PTSD – treatment for which was practically non-existent at that time. Without treatment options, those soldiers often ended up creating negative environments for their families. Homes broken by alcoholism, violence, and neglect were quite common. And women often were pulled into that as well. That environment can be extremely damaging to children, and it has certainly been looked at as a potential cause for the number of people who could have even potentially developed into serial killers.
And then you had the other societal issues of the 1960’s, 1970’s, and 1980’s. Cold war tensions were sky high, vietnam was vigorously protested, crime was skyrocketing in other areas (the drug trade and violent crime in poverty-stricken areas in particular), civil rights movements came to a head. Police were quite simply spread thin as-is. The resources just weren’t there.
To summarize, it was a perfect storm:
1. Travel was far easier and more accessible, meaning a killer could evade capture simply by spreading attacks across different jurisdictions
2. Police were struggling with resources and the volume of crime overall as is, not including serial killer activity
3. Police in different jurisdictions generally didn’t communicate about cases unless there was cross-jurisdiction involvement on a single case. An officer aware of a peculiar killing in one area would likely not have been made aware of a similar killing four towns down the road
4. The long term effects of the war on families meant a higher than usual number of children being raised in harsh conditions known to foster certain traits common in serial killers. Not necessarily increasing the number of serial killers, but certainly increasing the number of *potential* serial killers
Essentially, a person already predisposed to becoming a serial killer had significant opportunity access and several conditions which helped them evade capture. Conditions we don’t particularly see anymore.
So what changed?
Well, a few things.
For one, technology has improved. CCTV cameras are found in most public places, people carry phones on their person which can enable location tracking, and the technology of forensics has improved significantly. DNA evidence and other high-tech solutions have made it easier to identify killers where traditional would struggle.
Another reason is a change in overall behavior, largely in response to serial killers and other aspects of the high crime zeitgeist of the latter half of the 20th century. People are *far more proactive about their personal safety. Emergency calls on dates, prioritizing visible public areas when engaging in romantic relationships, installing home security systems, etc.
A huge example of that is the decline of hitchhiking. What was once a rather commonplace activity has almost completely died out (both people offering rides and people accepting them) because of serial killers like Ted Bundy.
Serial killers *very frequently* start with lesser crimes first, and tough-on-crime policies mean that a potential serial killer is much more likely to have already been in the system before they start killing. This guarantees access to rapid identification materials – DNA and fingerprints, for instance. It means serial killers can often get captured much more quickly.
Police forces, thanks to modern technology, also have the ability to communicate cross-jurisdiction much more easily now. Which means two potentially related cases can be connected much quicker then previously.
And other changes play a part as well. Mental health services have improved significantly in the past 30 years, meaning potential serial killers are more likely to get the help they need *before* they develop into killers. Child protective services and other policy-movements to help get kids out of dangerous environments have also seen a boon. And an overall increase in police resources have allowed police forces to reduce local crime and increase their capacity to look into cases like those initiated by serial killers.
None of this is to say that serial killers can’t still develop and evade capture. But their ability to do so has been *significantly reduced* in the past few decades.
