Adam Lanza, the 20-year-old responsible for the death of 20 children and 7 adults at the Sandy Hook Elementary, is now to have his DNA examined by geneticists working with the University of Connecticut.
It is their hope that this man's DNA will display signs of mutations and/or abnormalities, and that this will somehow help explain his killing spree.
Thus, the geneticists are looking for genetic clues that might help explain his aggressive nature and link Adam Lanza's behavior to mental illnesses, sources report.
However, other scientists wish to draw attention to the fact that not just genetics, but also environmental factors, must he held accountable for this 20-year-old's outburst.
“I think it's much more than a simple genetic answer, but an interplay between genetics and environment,” said Dr. Heidi Tissenbaum, a geneticist presently working with the University of Massachusetts.
In other words, should one only focus on genetics when trying to explain aggressive behaviors, certain people might find themselves unnecessarily stigmatized.
