The below is lifted straight from California jury instructions on an Invol manslaughter. Just for reference:
When a person commits an unlawful killing but does not intend to kill and does not act with conscious disregard for human life, then the crime is involuntary manslaughter. The difference between other homicide offenses and involuntary manslaughter depends on whether the person was aware of the risk tolife that his or her actions created and consciously disregarded that risk. An unlawful killing caused by a willful act done with full knowledge and awareness that the person is endangering the life of another, and done in conscious disregard of that risk, is voluntary manslaughter or murder.
An unlawful killing resulting from a willful act committed without intent to kill and without conscious disregard of the risk to human life is involuntary manslaughter.
The defendant committed involuntary manslaughter if:
1. The defendant committed (a crime/ [or] a lawful act in an
unlawful manner);
2. The defendant committed the (crime/ [or] act) with criminal
negligence;
AND
3. The defendant’s acts caused the death of another person.
[The People [also] allege that the defendant committed the following
lawful act with criminal negligence: Criminal negligence involves more than ordinary carelessness, inattention, or mistake in judgment. A person acts with criminal negligence when:
1. He or she acts in a reckless way that creates a high risk of death
or great bodily injury;
AND
2. A reasonable person would have known that acting in that way would create such a risk.
In other words, a person acts with criminal negligence when the way he or she acts is so different from the way an ordinarily careful person would act in the same situation that his or her act amounts to disregard for human life or indifference to the consequences of that act.
[An act causes death if the death is the direct, natural, and probable consequence of the act and the death would not have happened without mthe act. A natural and probable consequence is one that a reasonable person would know is likely to happen if nothing unusual intervenes. In deciding whether a consequence is natural and probable, consider all of the circumstances established by the evidence.]
