Chauvin was found guilty of second-degree unintentional murder, third-degree murder and second-degree manslaughter last week after a three-week trial and 10 hours of jury deliberation.
Minnesota law says that he will only be sentenced for the most serious count — second-degree murder — which carries a max prison sentence of 40 years.
Chauvin waived his right to have the jury determine his prison sentence, so Hennepin County Judge Peter Cahill will determine it on June 25.
Sentencing guidelines in Minnesota recommend 12 1/2 years for someone convicted of second-degree unintentional murder who has no criminal record.
But prosecutors are pushing for Judge Cahill to go beyond that advisory range in what is known as an “upward sentencing departure.” The state is citing several aggravating factors in pushing for a longer sentence, including that Chauvin was a police officer who “abused his position of authority,” and that the murder was committed in front of a 9-year-old child.
“We believe there are aggravating factors and the sentence should exceed the sentencing guidelines,” Minnesota Attorney General Keith Ellison said after Chauvin was convicted.
Under Minnesota law, prisoners with good behavior become eligible for parole after they serve two-thirds of their sentence. So if Chauvin is sentenced to 15 years, then he would be eligible for release after 10 years.
Chauvin is being held in Minnesota’s only maximum-security prison, Oak Park Heights, which is about 25 miles east of Minneapolis. He is currently being held in a single cell for his own safety.
