Under Tennessee criminal law , there are several different types of homicide or murder charges from first degree murder to criminally negligent homicide. Criminally negligent homicide is the least severe charge of murder . It is a Class E felony which carries a full range of punishment of 1 to 6 years in jail .

To prove a criminally negligent homicide , the evidence can show an intentional or knowing killing which is unjustified or a killing which was proximately caused by the reckless or criminally negligent conduct . However , that answer needs more  to determine it’s true meaning.

Here it is right from the Tennessee Code ;

(d)  “Criminal negligence” refers to a person who acts with criminal negligence with respect to the circumstances surrounding that person’s conduct or the result of that conduct when the person ought to be aware of a substantial and unjustifiable risk that the circumstances exist or the result will occur. The risk must be of such a nature and degree that the failure to perceive it constitutes a gross deviation from the standard of care that an ordinary person would exercise under all the circumstances as viewed from the accused person’s standpoint.

Now I just need to know what gross deviation from the standard of care means .
