Final answer:
The district attorney would most likely assign a charge of voluntary manslaughter in this case. Voluntary manslaughter involves intentional killing with mitigating circumstances.
Step-by-step explanation:
The most likely type of prosecution the district attorney would assign in this case is voluntary manslaughter.
Voluntary manslaughter is the intentional killing of another person, but with mitigating circumstances that reduce the severity of the charge. It typically involves a sudden provocation that induces rage or an uncontrollable urge to harm or kill, resulting in the death of another person.
In this case, the man struck another man in a rage of anger, instantly killing him. Although the act was intentional, the fact that it was committed in a fit of rage would likely lead to a charge of voluntary manslaughter, rather than a higher charge like first or second degree murder.
