That looks like a serious headache. I found this photo on Facebook it was reported that Rodrigo Moreira was a victim of a motorcycle robbery and the robbers shot the him in the head after taking his motorcyle at gun point. There is little information as to the circumstances of the robbery. Was the Rodrigo wearing a helmet? How far away were the shooters? When did they shoot him? Was it point blank or did they shoot him as they fled?
From the photo it appears to be a .45acp bullet lodged into the Rodrigo Moreira’s skull. If he was not wearing a helmet then the only explanation as to his survival would be the cartridge was severely under powered. I vaguely recall a story about criminals policing up brass after a shooting, whether it was by the police or criminals, and they use the brass to reload ammo. If this were true then it is conceivable that Rodrigo may have been one lucky guy to have been shot by a shoddy reload.
