Given that Kaarma told police that he shot blindly into the darkness and never saw the person in his garage until he'd killed him, yeah, it could have been anyone, including a kid.
In their rebuttal, prosecutors called Kaarma the aggressor and told the jury it is sickening that he adjusted his aim for the final gunshot. Witnesses testified Kaarma fired three times at roughly the same level, but readjusted and raised his aim for the shot that killed Dede.Seems to me that whatever witnesses there were are biased witnesses, not to mention accessories to Dedes attempt at burglary.
