Keith Ellison said in a legal brief filed in Minnesota's Hennepin County District Court.

The State respectfully requests an aggravated sentence for Defendant Derek Chauvin, a former police officer convicted of second-degree murder, third-degree murder, and second-degree manslaughter in connection with the death of George Floyd. [case law citations] The facts proven beyond a reasonable doubt at trial demonstrate that five aggravating factors support an upward sentencing departure. ...

"Mr. Floyd was treated with particular cruelty . . . Defendant continued to maintain his position atop Mr. Floyd even as Mr. Floyd cried out that he was in pain, even as Mr. Floyd exclaimed 27 times that he could not breathe, and even as Mr. Floyd said that Defendant's actions were killing him," Ellison said.
[...]
[Defense attorney Eric Nelson] said Floyd was not treated with particular cruelty, saying that there is no evidence that the assault perpetrated by Chauvin involved gratuitous pain that's not usually associated with second-degree murder.
[...]
Prosecutors did not specify how much time they would seek for Chauvin.
