He would race to nearby mountains, wait for his prey, and quickly return to work after his kill. On the way to work, he would later confess, suddenly an intense desire to kill would overpower him. Thomas Dillon, a married and working man without any apparent evidence of mental illness, terrorized southern Ohio for several years in the early 90's, and in some peculiar ways reminds me of the Washington phantom sniper.ĭillon was a textbook example of a lone serial killer that was driven to hunt hunters. The "simple serial killer," for instance is one type. Although there are as many types of serial killers as there are cancers, three major types have been recognized: Serial killers, delusional serial killers, and sexual predator serial killers. It would be wrong to view all serial killers as the same. Most of them have abused pets or other animals as children or young adults. Often they are white men between the ages of 20 and 50 and of average intelligence. Famous serial killers such as Ted Bundy, Jeff Dahmer and Dennis Rader grew up in healthy households with supportive family members.A few basic facts about serial killers are helpful. Furthermore, though serial killers like Charles Manson were abused and neglected as children, the list of serial killers with a normal childhood is long. We cannot exclude that childhood abuse or neglect may be a factor in making psychopaths commit crimes, but it's not a likely contributing factor to psychopathy itself. But anxiety disorders are typically associated with either greater connectivity between the amygdala and the vmPFC or a dysfunction of vmPFC that makes it unable to modulate negative information from the amygdala. Early childhood abuse or neglect often leads to posttraumatic stress disorder or phobias (e.g., in terms of making commitments). But after many years of investigating the minds of psychopaths, researchers have been unable to find any factors that could contribute to the development of psychopathic traits. Social factors have some (even if only small) role to play in generating psychopathy. Though they feel physical pain, they are not themselves in a position to suffer from emotional hurts. They do not feel sad when other people suffer. They do not feel nervous or embarrassed when they are caught doing something bad. This fits well into the picture we have of psychopaths.

When the connectivity between these two regions is low, the processing of negative stimuli in the amygdala does not translate into any strongly felt negative emotions. Brain scans revealed that psychopathy in criminals was associated with decreased connectivity between the amygdala, a subcortical structure of the brain that processes negative stimuli, and the ventromedial prefrontal cortex (vmPFC), a cortical region in the front of the brain that interprets the response from the amygdala. A possible candidate for this abnormality has recently been identified in a study at the University of Wisconsin, Madison. If psychopathy is genetically determined, one should expect some abnormality in the brain, the immediate source of psychopathic traits. This leaves open the possibility that psychopathic traits are largely genetically determined. Though only a couple of hundred mutations take place during early fetal development, the mutations likely multiply over the years, leading to vast genetic differences. Recent genetic studies of twins indicate that identical twins may not be as genetically similar as hitherto assumed. This percentage indicates that psychopathic traits are due more to DNA than to upbringing. The Minnesota twin study has shown that psychopathy is 60 percent heritable. The Minnesota Twin Study is a project originally led by Minnesota Professor of Psychology Thomas Joseph Bouchard, Jr. One of the best sources of information about whether traits are a result or nature of nurture comes from the Minnesota Study of Twins Reared Apart. We don’t even have a satisfactory answer to the question of whether psychopathy is a product of Mother Nature or a feature of upbringing. The causes of psychopathy remain a mystery. These creepy Ted Bundy quotes patently summarize the main traits of a psychopath: A callous, exploitive individual with blunted emotions, impulsive inclinations, and an inability to feel guilt or remorse.
