Virginia Model Jury Instruction (2013)
33.610 Criminal Negligence–Definition
The gist of involuntary manslaughter is criminal negligence. It must be shown that the negligence of the defendant was gross or culpable negligence. Gross or culpable negligence is that which indicates a callous disregard of human life and of the probable consequences of his act. Criminal liability cannot be predicated upon every act carelessly performed merely because such carelessness results in the death of another. In order for criminal liability to result from negligence, it must necessarily be reckless or wanton and of such a character as to show disregard of the safety of others under circumstances likely to cause injury or death. Unless you believe from the evidence beyond a reasonable doubt that the defendant was guilty of negligence so culpable or gross as to indicate a callous disregard of human life and of the probable consequences of his act, you cannot find him guilty of involuntary manslaughter.
