With about a dozen family members looking on, Darrell Zahne pleaded guilty Friday to the lesser charge of manslaughter and aggravated assault in a fatal crash that took the life of a Kingman high school girl in October.
Zahne, 23, had originally been charged with second-degree murder for the Oct.
1 crash that killed Christina Burcham, a 16-year-old Kingman high school student.
Zahne could face up to 21-1/4 years in prison when he is sentenced April 23 by Superior Court Judge Richard Weiss.
The crash also seriously injured Burcham's fiancé, Robert Goodhue, 18, who was listening but did not speak in court during Friday's plea agreement.
Chief Deputy County Attorney Jace Zack said he was satisfied with the plea, which he had proposed to the Burcham family.
"This gives the judge plenty of room to enter an appropriate sentence," Zack said.
Bruce Fowler, a family friend of the Burchams who also attended the court proceedings, also seemed satisfied with the plea.
