Not disagree but were does "intentional" come in?
You need to read further that the one line you quoted on that page
Minnesota law prohibits intentional and unintentional killings under most circumstances. Those killings prohibited as second-degree murder include:
Killing a human intentionally, but without premeditation (not thinking about or preparing for before)
Killing a human while committing or attempting a drive-by shooting
Causing someone’s death without intending the death of anyone, while committing a felony other than criminal sexual conduct (rape or sexual assault which would be first-degree murder) or a drive-by shooting
Causing a death unintentionally, while intentionally inflicting or attempting to inflict great physical harm on the victim when the murderer is currently restrained by a protection order (including for domestic violence, harassment, divorce, or any similar protection order) and the victim was the protected party in that order
Third-degree murder in Minnesota is causing someone’s death by one of two ways:
A depraved heart or mind murder, which places others in eminent danger of death and disregarding human life (such as shooting a gun into a crowd for fun, but not intending to kill anyone)
Causing someone’s death by selling, giving away, or administering a Schedule I or II controlled substance (such as selling someone adulterated heroin that kills them)
