Scientists at the University of Connecticut plan to examine the DNA of the Connecticut elementary school shooter Adam Lanza.
In what's being called the first of its kind study, geneticists will look at the 20-year-old's DNA to see if there are biological clues as to why Lanza carried out the deadly massacre.
While researchers haven't made public their plans, some experts speculate scientists will look for mutations that might be associated with violence or mental illness.
The plan is getting mixed reviews in the science community. Some say studying genetic abnormalities could help further research on human violence.
Others believe such a study could draw false conclusions on the genetic causes of mental illness.
