The Nebraska attorney general’s office says 19-year-old Brayan Galvan-Hernandez entered the plea Tuesday in a deal with prosecutors. Authorities say Galvan-Hernandez and 26-year-old Andres Surber, both of Wakefield, fatally shot 41-year-old Kraig Kubik, of Emerson, on Nov. 1, 2016.
In April, a judge ruled that Surber was not mentally competent to stand trial.
Kubik was shot in the back of the head and his dismembered body was found in a culvert in rural Cedar County four days after he was reported missing. Other parts of his body were found in a car trunk.
