MINNEAPOLIS (AP) - A Hennepin County jury has convicted a 25-year-old man of fatally shooting another man in the victim's backyard.

Diamond Griffin of Minneapolis is set to be sentenced in December to life in prison with parole for the July 2013 killing. He would be eligible for parole after serving 30 years in prison.

Prosecutors say they will ask that he receive three consecutive sentenced for his convictions this week of first-degree murder, first-degree attempted murder and second-degree assault.

Authorities say Griffin tried to rob 38-year-old Francisco Benitz-Hernandez, his brother and his brother-in-law at gunpoint while they were sitting in the backyard. They say he demanded their money and cellphones and began shooting after they said they didn't have anything.

Griffin killed Benitz-Hernandez and wounded one of the other men in the arm.
