Does the genotype decide who will become a murderer?

To answer this question, researchers at the University of Connecticut, USA are working on a genetic research project of Adam Lanza, who has been firing consecutive shots at Sandy Hook Elementary School in the United States. killed 27 people.

According to experts, geneticists can find mutations in genes associated with mental illness that increase the risk of violence. They believe that mass killings go far beyond normal behavior and must be related to genetic changes.

Did Gene decide who became a murderer?

Meanwhile, some other scientists are concerned that the study will lead to stigma against people who have never committed a crime, but who have mutated genes like murderers. They also claim that there are hundreds of genes involved in violent behavior, not to mention the effects of the external environment, which can interact with each other in difficult ways to predict.'It is hard to imagine that there is a genetic factor that is common among serial killers , ' said Dr. Robert C. Green of Harvard Medical School.

Previously there have been many studies of genetics for violent and murderous people and controversial. However, this seems to be the first time scientists have studied the genome of serial killers in detail and the research has been appreciated by many scientists.'The genetic record of the person who committed the crime related to violence may play an important role. Whether or not the release of criminals was previously based solely on mental assessments. Genetic evaluations can add certainty to these decisions, ' commented Dr. Skene of Duke University.

Another idea is that knowing the violence killer's genome will sometimes be used. The stored DNA and frozen cells will one day become useful clues.
