Understanding the psychology of serial killers is only one side of the coin. The other side involves how the criminal justice system responds once such killers are caught. From legal procedures and sentencing, to mental health evaluations, and their lives behind bars, this chapter explores the intersection of criminology, law, and justice in handling serial offenders.
How Different Countries Sentence Serial Killers
The approach to punishing serial killers varies dramatically across legal systems. While most nations treat serial murder as the gravest offense, the form of punishment can reflect political, cultural, and ethical values.
United States
• The death penalty is a common sentence in states where it is legal.
• Some serial killers, like Ted Bundy, were executed.
• Others, like Jeffrey Dahmer, received multiple life sentences.
• Sentencing often includes no possibility of parole because of the
nature of the crimes.
Pakistan
In the case of Javed Iqbal, who confessed to killing 100 children, the court sentenced him in March 2000 to die in the same way he had murdered his victims. He was found dead in prison before the sentence could be carried out. Death penalties and long-term imprisonment are standard for murder in Pakistan, though execution methods can face international criticism.
Europe
• Most European countries, including Germany and Norway, do not
allow the death penalty.
• Sentences usually focus on life imprisonment with periodic
reviews and mental evaluations.
• In Norway, mass murderer Anders Breivik received a 21-year
sentence that can be extended indefinitely, sparking global debate.
Japan and China
• These countries allow capital punishment for severe crimes,
including serial murder.
• Trials are often swift, and executions may be carried out with
limited public information.
The Insanity Plea and Psychological Evaluations
The legal definition of insanity and its use in serial-murder cases are discussed in Chapter IX. In brief, a defendant must show that he or she could not understand the nature of the act, or could not tell right from wrong at the time of the crime. The plea is rarely successful: some defendants raise it hoping to avoid harsh sentencing, but most serial killers are found legally sane.
Examples:
• Ed Gein was found not guilty by reason of insanity and committed
to a mental institution.
• In a famous non-serial case, John Hinckley Jr., who shot U.S.
President Ronald Reagan, successfully used the insanity plea —
sparking public backlash and tighter legal definitions of insanity.
Psychological assessments are carried out by forensic psychologists, who
evaluate:
• Mental disorders
• Risk of reoffending
• Competence to stand trial
If found unfit to stand trial, the defendant may be sent to a psychiatric
facility rather than prison — sometimes for life.
Role of Forensic Psychologists in Court
Forensic psychologists are key players in legal cases involving serial killers. Their tasks include:
• Conducting risk assessments
• Providing expert testimony on mental state
• Helping determine motive and behavioral patterns
• Assisting law enforcement in offender profiling
Their evaluations can influence whether the defendant is considered criminally responsible or receives an alternative sentence (e.g., psychiatric confinement).
Prison Life of Serial Killers — Can They Be Reformed?
Once convicted, serial killers are usually placed in maximum-security prisons or psychiatric hospitals. Many are kept in isolation due to the danger they pose to other inmates and themselves.
Key Realities:
• Jeffrey Dahmer was murdered by another inmate.
• Dennis Rader (BTK) is serving ten consecutive life sentences.
• Aileen Wuornos became increasingly unstable and was eventually
executed.
While some killers appear to show remorse or undergo therapy, true rehabilitation is rare. The deep-rooted psychological issues and lack of empathy make treatment difficult. In many cases, the risk of reoffending is too high to allow for release.
In conclusion, while society may never fully understand the mind of a serial killer, the legal system aims to ensure justice through structured procedures, mental evaluations, and appropriate sentencing. For criminology students, this chapter emphasizes the crucial role of law, psychology, and ethics in shaping responses to some of the most unsettling crimes known to mankind.
