Jonathan Barfield has been sentenced to 20 years in prison for manslaughter in the shooting death of his girlfriend.

The 19-year-old Barfield was convicted in July in Harrison County in the slaying of 17-year-old Tiffany Talley. He was sentenced Monday by Circuit Judge Lisa Dodson.

Prosecutors say Talley was found shot to death December 27, 2006, inside Barfield’s trailer in Gulfport.

Barfield maintains the shooting was an accident.
