And he felt the first stirrings of arousal over this. It was exciting to him to see a woman helpless, and it was the beginning of his ideas about women that what he wanted from them was to keep them trapped and helpless and looking to him in terror. That became imprinted in his mind and became the image he was always after. But he was really thirsty for that kind publicity of sorts. And the oldest is the guinea pig. Rader has always maintained that he was not physically or sexually abused as a child, according to an ABC News interview with his daughter, Kerri Rawson.
The truth of what caused Rader to become the BTK killer may never be fully known. But I think I got Rader pretty well. By Amy Beeman. Updated May 24, at pm. I allow Heavy. Disagree Agree. Notify of.

The present study uses a broader categorization, such as those designed by Holmes and Holmes Although this definition covers a spectrum of abuse, the three main types defined in the present study are physical, sexual, and psychological abuse.
Physical child abuse relates to acts that cause actual physical harm or have the potential for harm. Sexual abuse is defined as those acts in which a child is used for sexual gratification.
Psychological abuse includes the lack of an appropriate and supportive environment or acts that have an adverse effect on the emotional health and development of a child. It is possible that this is due to habituation and tolerance of pain, depending on the extent to which the abuse had been experienced as violent or painful Joiner, A method is needed that can systematically link and sequence childhood abuse with typology of the criminal and crime scene behaviours.
The present study provides this novel methodological approach to understanding the link between childhood abuse and later serial killer behaviour. BSA, also referred to as lag sequence analysis, is a method for investigating how chains of behaviours and events are linked over time. Behaviour Sequence Analysis involves the study of transitions between behaviour pairs Marono et al. Sequences can be on large lifetime, e. In lag-one BSA, which the present study uses, the antecedent behaviour e.
Obviously, there are intervening behaviours and events through the lifetime; however, the purpose of the present study is to highlight BSA as a method for understanding homicide and connecting established risk factors and behaviours. This provides a simplified model of types of abuse linked to type of murders. Put simply, a BSA will determine how likely it is, compared to chance, that a sequitur occurs following an antecedent.
Sequence Analysis is not limited to only two behaviours; it is possible to analyse the pattern between potentially unlimited numbers of behaviours from the start to end of a sequence. The present study uses a BSA approach to investigate the effects of different types of early childhood abuse physical, psychological, and sexual abuse on later serial killings.
The pattern of actions explored begins with this early abuse, leading on to the typology of the serial killer. This is included in the analysis to indicate links between abuse and typology, rather than direct sequential effects. The next behaviour explored was the crime scene behaviour — such as how the victim was killed and what was done with the body.
Thus, the sequence from early childhood abuse, typology of the killer, and crime scene behaviours was analysed. While formal hypotheses are not made, owing to the novel nature of the research, several expected links can be outlined.
It is also likely that individuals who have experienced early physical abuse will show a greater amount of violence — for example, signs of torture and overkill infliction of excessive and unnecessary violence.
An all-male sample of serial killers with a documented history of childhood abuse was collected. The dates of first kill ranged from to The date of last kill ranged from to As the sample had been obtained from secondary sources and so does not contain any studies with human participants, ethics approval was not needed.
The sample was split according to the type of abuse experienced in childhood. Power killers were those who derived pleasure from having complete control over their victims.
Financial gain killers were those who killed for motivations based on the accumulation of goods or finances. Anger killers were those who killed for motivations that stemmed from feelings of anger, frustration, or betrayal, whether real or imagined. The overall methods used across kills was also recorded for all killers. Percentages of participants for each individual were calculated at each stage.
Given the straightforward nature of the task, there was no ambiguity over responses or coding. The typology of serial killers was assessed by forensic psychologists. After data were coded into chains of discrete behaviours and categories, data were entered into the statistical software R R Core Team, and analysed using a behaviour sequence analysis program developed by the researchers.
The main stage of BSA is to focus on the transitions between pairs of behaviours. Transition frequencies between antecedents and sequiturs are calculated, and chi-square analyses are indicated if these transitions occur above the level of chance. State transition diagrams can then be drawn, which indicate pairs of behaviours with high standardised residuals SR.
It is important to note that while pairs of behaviours can be connected to form longer chains, the analyses are only on pairs of behaviours. Longer chains, though intuitively appealing, are actually limited in terms of generalizability, owing to over-fitting of data.

There did not seem to be a strong connection between financial gain and any type of abuse or combination of abuse, as it was infrequent in all cases, particularly the experience of all three combined.
There was no strong pattern between any single type of abuse and anger typology, and only 23 subjects classified as this typology. An additional benefit of the BSA approach is that particular cases can be highlighted and analysed individually. For instance, the following analyses focused on each type of abuse sequence by itself. This allows researchers and investigators to refine their search parameters and to begin narrowing in on particular sequences based on evidence or interests.
There was also evidence of overkill, and in all cases where overkill occurred, the body had been left at the crime scene.

Unlike the other types of abuse, sexual abuse was linked to all four typologies see Figure 4.

The outcome is an insight into the sequential chains that different types of abuse result in for an individual.
Within the current dataset, results indicate that different types of abuse affect later typologies and murder behaviours. Previous literature suggests that early physical abuse leads to later aggression and violence Widom, Current results partially supported this.
For example, mutilation, torture, and binding the victim were more typical of serial killers who had experienced sexual abuse. Furthermore, those who had been sexually abused rarely showed evidence of overkill, and the murders tended to be carried out quickly. This was not the case for both physical and psychological abuse, as both showed evidence of overkill.
Furthermore, all recorded murders were carried out quickly by those who were classified as motivated by power. There was also no evidence of any torture, mutilation, or overkill. Therefore, killers see the act of killing as a necessity, rather than obtaining any enjoyment out of the kill, per se. These are achieved by approaching a victim who is not expecting an attack.
They use drugs such as sedatives to weaken their victims then kill them Mitrione. As expected of a normal person, serial killers do not feel guilty after killing innocent people. They do not consider the killing as a bad thing as mentally it is normal to them.
Some are haunted by their doings later but this intensifies the urge to kill again. They do not feel pity for their victims even when they shout and scream. They also know the right people to provide them with weapons and fake documents to use when committing crimes Stewart. Welcome to the world of case studies that can bring you high grades!
