Teens who've killed

race? but it hasnt been reported...yet

Race - it's genetic. Violence, uncontrolled rage, and other anti-social can be derived from genetics.
Two conditions need to be meet:
1. They have the "warrior" gene
59% of African-Americans have it - compared to 34% of Caucasians.
But that means nothing unless the 2nd condition is also true.
2. They came from a childhood of violence, deprivation, abuse, neglect etc.

Then that anti-social violent behavior kicks in.

I'll bite and pretend you actually understand genetics and molecular biology: How did they control for any other variables such as other regulatory genes that regulate the gene, the gene possibly being related to some other behavior or something else entirely along with learned behavior and other environmental stimuli? I'll wait.
