@Jack Burton informs me that these things vary by state and that I was wrong to say "(in the US, by comparison)" and then specify anything at all.
It will depend on the law there, as we know. But in some states here unintentional death can be classified as second degree murder, and there are places where negligent homicide is on the books. But reckless homicide would do it.
Second-degree murder is typically murder with
malicious intent but
not premeditated. Where it would be applicable would be jurisdictions where the mens rea of the defendant is: not restricted to intent to kill, but encompasses
intent to inflict serious bodily harm, or
act with an abandoned heart (e.g., reckless conduct lacking concern for human life or having a high risk of death).
