The Behavioral Analysis Unit, or BAU, evolved from the FBI's Behavioral Science Unit,
or BSU.
The BSU is founded in 1972 under J. Edgar Hoover in the last days of his long reign as
director of the FBI.
The unit was designed to understand, profile, and study criminal behavior,
specifically in response to the rise of violent crime during the previous decade.
The original unit was composed of just 11 members.
The unit's goal was to help law enforcement understand the criminal mind,
especially the minds of serial killers.
Some of the most notable members of the early BSU included agents John Douglas and Robert
Ressler, along with forensic nurse and criminologist Dr. Anne Burgess.
Part of the early work of BSU agents included traveling to different prisons and interviewing
serial predators. In these interviews, they gathered information on their crimes, how they planned them,
details remembered from the time of committing the crime, their motivations, and how they disposed of
evidence. Through these interviews and research, they coined the term serial killer, for those who
repeated murderers in a repeated or serial cycle. Noted predators that they interviewed included
Edmund Kemper, who was known as the co-ed killer and has been confirmed to have killed at least
eight women, John Wayne Gasey, otherwise known as the clown killer, who had been confirmed to
have killed at least 33 young men, and David Berkowitz or the son of Sam, who was confirmed
to have killed at least six people and injured others. They used information from these interviews
to compile a database of information that would aid in understanding and predicting future criminal
behaviors, as well as the type of person who would commit the crime. The database was considered to be
complete in 1979 after Douglas and Ressler had interviewed 36 different predators. After completing
this database, profilers were then sent
out into the field to consult on active investigations.
These consultations were done through a technique called criminal profiling.
Profiling is done by using the behavior and actions done during the crime
to create a profile of the type of person who could have committed the action.
Profiling can help narrow down the pool of suspects during an investigation
and help create a picture of these psychological characteristics the killer or offender could have.
Additionally, behavioral analysis can be used to find the motive behind a crime,
There are often many behavioral clues left at a crime scene that can help provide insight into the mind of the criminal.
In 1985, the Behavioral Science Unit at the FBI Academy was officially established by the National Center for the Analysis of Violent Crime, or NCAVC.
This meant that the BSU received more resources and support for investigative and operational activities,
including additional training programs and increased research efforts.
Part of this was the creation of VICAP,
or the Violent Criminal Apprehension Program, which held the data from different criminal cases,
including the earlier research done by Douglas and Wessler. With VICAP, investigators had an easier
time identifying and matching different aspects of the crime to the profile of the offender.
The behavioral analysis unit of today was established in 1997 as part of the NCAA and the FBI's
critical incident response group. Through this, they aid in investigations across the country and at U.S.
embassies around the world, as well as assisting other groups within the FBI.
The modern BAU is split into five different units.
Unit 1 deals with counterterrorism, bombing, and arson cases.
Unit 2 analyzes white-collar crime, including public sector corruption and cybercrime.
Unit 3 specializes in crimes against children.
Unit 4 works on analyzing crimes against adults.
And finally, Unit 5, which conducts research on behavior and provides instructions for law
enforcement to apply behavioral analysis in their investigations. The BAU primarily focuses on preventing
violence by identifying various concerning behaviors. Through requests from different agencies,
the BAU will provide assistance through consultations. These can be in-person and on-site or
through simple phone calls. These consultations allow the BAU to assist with criminal investigation
analysis. This analysis is completed through a behavioral and investigative lens. To give you an idea of
how criminal analysis works. I'll provide an example of one of the many behaviors profilers look for
when analyzing a violent crime. When arriving at the crime scene, profilers can examine whether or not
an offender is considered organized, disorganized, or mixed. Determining if an offender is one of
these three categories can help assess their intelligence, job type, relationship status, and mental
status. An organized offender is typically someone who is intelligent, likely, socially skilled,
and more than likely employed, likely in a committed relationship, and probably has no history
of mental illness. When determining if an offender is organized, investigators will look for
whether a weapon was brought to the crime scene, if there's any biological evidence like
DNA left behind, if the victim was physically constrained, or if the body was hidden or concealed.
Disorganized offenders are the opposite. They are more likely. They are more likely.
likely to have a history of mental illness, could be employed, but the job would likely to require
little skill, likely to not be very intelligent, struggle with real intimate relationships, and do
not function well in society. This is shown at the crime scene through a general feeling of
disorder, the crime scene not appearing to be planned, including the weapon being obtained from
the crime scene, DNA being left behind, and the body being disposed of poorly. Another key aspect
of profiling that behavioral analysis look for is victimology. Knowing why a victim is chosen
can aid in finding the motivation behind the crime. There are many different reasons why a victim
could be chosen, including race, sex, age, lifestyle, and other aspects. Knowing these can be key
in identifying people most at risk for a crime and the psychology behind why the perpetrator
would pick that specific victim. Behavioral analysis can also be used to figure out the signature
and the modus operandi or MO of the criminal.
The MO is simply the actions the perpetrator took when committing the crime.
So if a killer were to bring a weapon to the crime scene,
you may be able to conclude that part of their MO would be threatening the victim prior to the attack.
Another part of the ammo could be if the residence of the victim was staked out beforehand.
If the killer were to know that part of the victim's routine was to take a lunch break at home
when no one else was around,
they could be confident that there would be little risk in attacking the victim.
in that moment. Additionally, if there was little planning, it can also play into a profile.
If the scene shows a fight, or if the killer was interrupted, it can show that the criminal
was unprepared or did not premeditate the crime. Something as small as the killer being let
into the house without needing to break in can hint that the victim and killer knew each other,
or that the perpetrator made his appearance appearing non-threatening.
Knowing the ammo of a perpetrator can show crucial information about the relationship between the
victim in the killer. On the other side of the coin, finding a signature of the perpetrator
can also indicate information about their psychology and aid in creating a profile. A signature
can show a need or fantasy of the killer. This is most often found in serial murder cases
and is usually indicative that the killer needed to do something beyond the actual crime itself.
A signature can simply be posing the victim after the crime, taking an item, or deciding to
taunt the police. A signature is not always present at a crime scene, but it can be useful in the
investigation and psychological understanding of the perpetrator. Profiling can occur in different
phases of a criminal case. The first phase is the investigation. During this phase, profilers
see whether or not different crimes can be linked. They then see if the evidence can reveal if the
killer is organized or disorganized, the M.O., the signature of the perpetrator and the victimology.
All of these can be used to create a profile of the perpetrator's
characteristics, assess if they are likely to escalate their crimes, and develop a strategy
to catch the perpetrator. The apprehension phase is when the profile is used to narrow down
where to look for the criminal, what information should be revealed to the public, and the
reaction the criminal may have if caught. And the final phase is the prosecution phase. Here the
profiler would be considered an expert in the case. They will use the evidence to show how to connect
the perpetrator to the crime. There have been many high.
profile cases that the FBI's behavioral analysis unit has consulted on. But to illustrate how they
work, I'll look at one of their first and most notable cases, that of the serial killer Ted Bundy.
Bundy was a U.S. serial killer who was confirmed to have killed 20 victims, but he has confessed to
killing at least 30, and is suspected of having killed even more. Bundy's killings occurred across
state lines in different jurisdictions, and profiling was one of the main ways investigators managed to link
different murders together. This was done by analyzing the behavioral patterns at the crime scenes
and recognizing similarities amongst the victims. Resources like Vycap kept a log of the crimes that
occurred in different jurisdictions and linked patterns that appeared similar. In Bundy's case,
evidence of a serial killer first appeared in Washington State, with 10 women going missing
over the span of eight months. Then in Utah, a similar pattern appeared. Bundy was arrested and later
escape twice, but the pattern continued in both Colorado, where he was imprisoned, and later in
Florida. When he had escaped prison, the FBI was able to release a profile on his ammo, as well as
the type of victims he would be looking for. The FBI considered Bundy to be organized, evidenced by
his choice of weapon, and the ruses he used to lure his victims. They knew from his past murders
that Bundy would look for victims where young people were, most likely the beach. They also learned
from his victims that he would target younger brunette women with long hair that they parted down
the middle. By releasing this profile, they hope to have people on the lookout for someone of Bundy's
description at locations where he was likely to be while also protecting potential victims.
Before behavioral analysis and resources like Vycap, it would have been difficult to link crimes
across state lines as differing agencies would simply be unaware that a similar crime had taken
in place elsewhere. There are some controversies and problems with behavioral analysis and profiling.
The largest problem is that it isn't an exact science. There's no empirical evidence to show that it
works. There is fear of bias and assumptions being made which can lead to poor profiles based on
opinion. Many people consider it almost a pseudoscience. To be fair, however, it isn't something
that you can actually run a controlled experiment for. You can't let a serial killer run loose just to test to see
if you can find them. Despite potential downsides, the BAU is considered one of the FBI's most valuable
tools, having grown in manpower and research capabilities. They now mainly work in providing
aid and collaborating with different law enforcement agencies. The work of the Behavioral Analysis Unit
has had significant impact on the way law enforcement approaches and understands violent crime.
Criminal profiling has become one of the main tools that police departments and the FBI
used to understand criminal behavior and help bring criminals to justice.
