Following the tragic shooting of 20 children at a school in Newtown, Connecticut, in 2012, Connecticut's state medical examiner requested a full genetic analysis of the killer's genome. What do you think investigators might be looking for? What might they expect to find? Might this analysis lead to oversimplified analysis of the cause of the tragedy?

Key Concepts

Genetic Analysis

Genetic analysis involves examining an individual's DNA to identify genetic variations that may influence behavior, health, or predisposition to certain conditions. In the context of criminal investigations, it can help determine if there are hereditary factors that might contribute to violent behavior, although such interpretations can be complex and controversial.

Nature vs. Nurture

The nature vs. nurture debate explores the relative contributions of genetic inheritance (nature) and environmental factors (nurture) to human behavior and development. Investigators might consider how both genetic predispositions and life experiences shape an individual's actions, emphasizing that behavior is often the result of a complex interplay between these factors.

Oversimplification in Genetic Determinism

Genetic determinism is the belief that genes alone dictate behavior and traits, which can lead to oversimplified conclusions about complex human actions. In the case of violent behavior, relying solely on genetic analysis may ignore critical social, psychological, and environmental influences, potentially leading to misguided interpretations of the causes of such tragedies.
