I don't know about Minnesota. In Arizona (for instance), the jury can convict on the charged crime or any "lesser-included" crime. I'll glance at the Minnesota statutes and case law, and see if I can quickly figure it out. Edit: "Second-degree culpable negligence manslaughter is a lesser-included offense of first-degree premeditated murder." State v. Penkaty, 708 N.W.2d 185 (Minn. 2006) Although, it looks like there, the defense requested the manslaughter instruction, so I don't know if the prosecution can make the request...
