Twenty-three-year-old Brittany Jones also will serve two years on extended supervision. The La Crosse Tribune (http://bit.ly/1nLwib5 ) reports she has credit for 81 days.
According to court records, Jones picked up her boyfriend, Mitrel Anderson, minutes after police say he fatally stabbed 24-year-old DeMario Lee at a Kwik Trip store in June.
She drove the couple to Madison, where state agents arrested them the next day after police tracked them through cellphone records.
Lee's family called for a maximum sentence for Jones, testifying his death has devastated them.
Anderson argues he acted in self-defense. His trial is set to begin June 9.
