Cadveric Spasm

It was a murder case. The victim was killed by a gunshot. The inlet wound was located in his Right eye. The bullet trimmed and perforated his Right eyelid and eyeball. The soot blackened outer surface of the Right eyelid and the tattooing dispersed mainly on the right side of his face. It was a near shot. The medico legist conducted the post mortem examination and without further elaboration, he gave his opinion about the direct cause of death, which was obvious and easy in such cases. However, upon my reviewing these documented photos, I have noticed that the deceased was biting his lower lip centrally i.e. biting the lower lip with the upper central incisors which apparently was not noticed by the medicolegist during his first examination and autopsy.
