Man pleads guilty in drug-deal slaying

A 39-year-old man faces between 10 and 22 years in prison after pleading guilty Monday to second-degree murder for his role in the slaying of Arturo Arvizu, 26.

Raul Rene Martinez admitted he was involved in the kidnapping of Arvizu, who was beaten, shot and found dead in a vehicle in the 6000 block of South Fontana Avenue on Sept. 25, 2011.

Martinez, Arcadio Arias Chavez, Josue Hernandez and Elmer Barrera-Grijalva were indicted on one count each of first-degree murder and kidnapping in connection with Arvizu's death.

Martinez's attorney, Thomas Hippert, said Arvizu showed up at Chavez's south-side apartment to buy 150 pounds of marijuana and Martinez helped detain him in the apartment. Martinez is to be sentenced in July by Pima County Superior Court Judge Christopher Browning.

Chavez pleaded guilty to manslaughter and attempted possession of marijuana for sale and will be sentenced in June. Barrera-Grijalva and Hernandez pleaded guilty to second-degree murder and await sentencing.
