Exploring the Warrior Gene: Scientific Insights and Legal Defense

April 18, 2017

At Knox Defense, we stay abreast of scientific developments that may help our clients. One such development is the exploration of the Warrior Gene, scientifically known as the MAOA gene. This gene, located on the X chromosome, has been linked to increased susceptibility to violent behavior, especially in individuals with a history of childhood abuse.

Understanding the Warrior Gene

Scientific studies have shown that the MAOA gene plays a role in regulating neurotransmitters in the brain, which can influence behavior. Research suggests that individuals carrying a specific variant of this gene, combined with experiences of abuse during childhood, may be up to five times more likely to exhibit violent behavior. This genetic and environmental interaction can lead to what is sometimes referred to as the “Warrior Gene” effect.

Key Points from Scientific Studies

MAOA Gene Variant: The gene variant linked to violent behavior affects the metabolism of neurotransmitters such as serotonin and dopamine.
Childhood Abuse: Evidence indicates that the presence of this gene, along with physical, sexual, or verbal abuse during childhood, can significantly increase the risk of violent behavior.
Gender Specificity: Since the gene is located on the X chromosome, its effects are more pronounced in men, who have only one X chromosome, as opposed to women, who have two.

Legal Implications of the Warrior Gene

The potential use of the Warrior Gene in legal defense is grounded in scientific research and legal precedents. In Tennessee, the case of State v. Phipps allows individuals with mental conditions or disorders that do not amount to insanity to use their diminished mental capacity to negate specific intent in certain crimes, such as first-degree murder.

Diminished Capacity Defense

First-Degree Murder: Requires proving specific intent to kill. If the defendant’s mental capacity is diminished due to the Warrior Gene and a history of abuse, it may be argued that they lacked this specific intent.
Second-Degree Murder: A successful diminished capacity defense can reduce the charge from first-degree to second-degree murder, significantly altering the potential penalties. First-degree murder can result in the death penalty, life without parole, or life with parole eligibility after 51 years, whereas second-degree murder carries a sentence of 15-25 years for those without significant prior criminal records.
