Medications don’t make a person a killer any more than does a gun.
Studies done on people taking SSRIs (Selective Serotonin Reuptake Inhibitors) would indicate otherwise. A google search reveals information on these drugs that lead one to believe that some people may be negatively impacted by taking these drugs as they do change the brain chemistry.
IF the allegations that this kid had Asperger’s Syndrome and you add a SSRI that can remove inhibitions and reveal the true you, then you very could well end up with an unfeeling person capable of acting on hostile thoughts with no empathy or remorse.

What about all the mass killers that weren't on drugs? Drugs or lack thereof will not automatically turn a person into a premeditated mass killer.
