Case Study
When discussing serial killers an infamous name comes to mind and that name is Jeffrey
Dahmer. He is known for his horrendous and brutal murders that included sexual assault/rape,
dismemberment, cannibalism, and zombification of seventeen male victims (O’Meara, 2009).
Though this case is a little over 30 years old when Jeffrey Dahmer was finally caught, 1991 is
not that long ago but the advances and prevalence in psychopathology has progressed that could
explain his well-known behaviors (Gibson, 2022). In the depictions of Jeffrey Dahmer’s
background there were characteristics that he displayed throughout his life that are simultaneous
with the characteristics of a psychopath but also factors of mental illness. According to O’Meara
(2009) evidence directs to Jeffrey Dahmer being a victim of the biopsychosocial theory but this
paper will discuss other theories of psychopathology that could explain the behavior of Jeffrey
Dahmer and if there are treatment options that could assist individuals similar to Jeffrey Dahmer.
Theories of Psychopathology
Jeffrey Dahmer was described as a happy child until he had a traumatic post-surgery
recovery at the age of 4, from then on, he had become withdrawn (McEvoy, 2023). His parents
were absent in his life, his mother suffered from postpartum depression that led her to a drug
addiction and his father was unable to cope with it leaving his unstable wife with their children
the majority of the time (O’Meara, 2009). Although there was no physical abuse in the home
where Jeffrey Dahmer grew up, it was neglectful and stressful. At a young age Jeffrey Dahmer
developed an allure to animal bones and studied how to clean and preserve them which he then
began to collect large insects and animal skulls conserved in jars of formaldehyde (McEvoy,
2023). At the age of 14 Jeffrey Dahmer began to have compulsions towards necrophilia and
murder as well as began drinking and a few years later when his parents divorced it seemed to
3
have led these thoughts into actions and his drinking into a frenzy (McEvoy, 2023). In 1978, the
year his parents divorced, was the first time Jeffrey Dahmer committed murder and throughout
the years up until 1991 he continued and progressed into the serial killer he’s known as to this
day. Following Jeffrey Dahmer’s arrest in 1991, he openly discussed his role in the murders with
law enforcement and provided valuable insight for collaboration of scene, personal, and autopsy
findings to forensic pathologists and psychiatrists and to law enforcement personal throughout
the investigation (Jentzen, 2017). The meticulous scene investigation and autopsy examinations
sanctioned for evaluation of Jeffrey Dahmer’s motives, methods’, and mental state which
constructed a psychological profile characterized by a calamitous behavior in which his
collection of fetishistic memorabilia provide an expression of his deep equivocation and mixed
malevolence towards his victims (Jentzen, 2017). Exasperated with sexual immaturity and
repeated rejection Jeffrey Dahmer conveyed his hostility into a sadistic sexual behavior trait of
the psychopathology of a serial killer (Jentzen, 2017). The biopsychosocial model is a
combination of biological, environmental, psychological, and social factors that can generate a
mental disorder, in Jeffrey Dahmer’s case his defense attempted to plea for insanity because he
had schizotypal, psychotic, and borderline personality disorder (BPD) tendencies (O’Meara,
2009). However, in order for an individual to be found not guilty by reason of insanity they have
to be found incompetent and not understand the difference between right from wrong and in
Jeffrey Dahmer’s case the jury found him sane due to the malice aforethought, continuation, and
‘trophies’ (O’Meara, 2009). Explaining the background of Jeffrey Dahmer’s life is not to feel
sympathy but rather understand what can cause a person to commit murder.

According to O’Meara (2009) the psychiatrists and psychologists that evaluated Jeffrey
Dahmer believed he suffered from some form on mental illnesses which included BPD,
schizotypal disorder, and psychotic disorder. He would have benefited from early intervention as
many others with mental illnesses would. By receiving a proper diagnosis and seeking the
appropriate treatment Jeffrey Dahmer could have been helped and learned to control his impulses
and urges when he first began to notice them at the age of 14. If he learned to cope with these
thoughts they may not have turned into actions; however, that will forever be unknown in this
case. Although this case is unknown, individuals who suffer from the same or similar diagnoses
need to take the steps to prevent these illnesses from worsening. Psychotherapy and medications
would be beneficial for individuals who suffer from BPD, schizotypal disorder, and psychotic
disorder (National Institute of Mental Health, 2023; Mayo Clinic, 2022; & NHS inform, 2023).
Conclusion
The English idiom don’t judge a book by its cover is prevalent in this case as for many
other cases when discussing and analyzing theories of psychopathology. Jeffrey Dahmer was an
individual who seemed to be an overall normal individual with some quirks but underneath that
was an apathic serial killer. Despite his upbringing and mental illness, he was fully aware of his
actions and rightfully convicted. Although there may have been a different outcome in Jeffrey
Dahmer’s life if his mental state had been evaluated earlier in life, and he received the help he
needed, no one will know or can know for sure, but there is hope for other individuals who suffer
from similar experiences and diagnoses.
