You left out the elbow. Elbows from a superior position, or any position are deadly.

Elbows from a superior position, or any position are deadly.

No they are not. Only if you are lying on concrete, because of possibility of head injuries on impact with a hard surface when hit. Elbows mostly cause lacerations because the impact is usually not direct (i.e. is lateral). But have you ever tried hitting something hard with your elbow? Unless trained it is vastly more painful then punching, adrenalized or not (In fact it causes momentary paralysis of the arm due to the presence of the ulnar nerve there). I train Muay-Thai as a general hobby and hence the knowledge. Martin most likely punched him.

Good point. The DNA test report doesn’t provide specific locations for all the samples. Some from the shirt had Z’s DNA. The hoodie had only Martin’s. Other possibility is he just charged him, I see that done by our local gang bangers a lot.
