(ABC NEWS) Geneticists have been asked to study the DNA of Adam Lanza, the Connecticut man whose shooting rampage killed 27 people, including an entire first grade class.
The study, which experts believe may be the first of its kind, is expected to be looking for abnormalities or mutations in Lanza's DNA.
Connecticut Medical Examiner H. Wayne Carver has reached out to University of Connecticut's geneticists to conduct the study.
