ATLANTA (WAOK) – Geneticists at the University of Connecticut will study the DNA of Adam Lanza. He’s the 20-year-old who carried out a shooting spree at a Newtown, Connecticut, elementary school that left nearly 30 children and adults dead. This may be the first study of its kind. The genetics team will likely be looking for a possible mutation or abnormality in Lanza’s DNA that may have led to his deadly rampage. Some experts have concerns that the team’s findings might lead to bias against people with the same genetic characteristics as Lanza. A geneticist at the University of Massachusetts calls the study risky because researchers can’t conclude anything from looking at just one person.
