Two men accused of beating and shooting a man and leaving him to die in a car on Tucson's south side in 2011 were sentenced Tuesday to nearly two decades in prison.

Elmer Barrera-Grijalva, 40, and Josue Hernandez, 27, pleaded guilty to second-degree murder in the death of Arturo Arvizu, 26. Barrera-Grijalva received a 20-year sentence and Hernandez received 17 years.

Several of Arvizu's family members spoke at the sentencing, where they described Arvizu as a loving family man and single parent.

Family members also said they didn't believe the remorse expressed by Barrera-Grijalva and Hernandez was genuine and asked Pima County Superior Court Judge Christopher Browning to impose the maximum sentence.

Barrera-Grijalva apologized to the family at the sentencing. "I feel responsible and I'm willing to pay for what I've done," he said.

Two other men charged in Arvizu's killing have later sentencing hearings.

Arcadio Arias Chavez pleaded guilty to manslaughter and has a sentencing hearing scheduled for June 17. Raul Rene Martinez pleaded guilty to second-degree murder and has a hearing scheduled for July 1.
