Dwight Campbell, 26, and Clifton Wherry, 31, were convicted of first-degree murder on Oct. 8 for the death of Quintero, a 24-year-old former Marine, in the 2300 block of East 10th Street on Sept. 29, 2006.
Campbell, who's from Southern California, and Wherry, an Oakland man, also were convicted of the special circumstance of committing a murder during the course of a robbery.
Wherry worked for Brinks and was the driver of the armored truck at the time of the shooting. Prosecutor Mark Jackson said Wherry was the mastermind behind the robbery and Campbell was the shooter.
Alameda County Superior Court Judge Larry Goodman told Wherry today, "You're one of the lowest people I've dealt with" in his many years as a judge because he betrayed Quintero's trust in him.
Goodman said Wherry is "like a snake in the grass" because he thinks Wherry lied on the witness stand and has "no morality."
Goodman also had strong words for Campbell, telling him that he went from being "one of the finest" because he was in the Marines to "one of the lowest" for betraying Quintero.
Campbell's attorney, Lorna Brown, said in her closing argument in October that Campbell had a hard time finding a steady job after being honorably discharged and was recruited by a third man, William Stallings, another former Marine who had been his sergeant in Iraq, to participate in the robbery.
Brown admitted that Campbell shot and killed Quintero but claimed that a shotgun that Campbell was carrying went off by accident when Wherry suddenly stopped the armored truck.
Brown said Campbell thought his role would only be to move money from one location to another and that he wouldn't be technically involved in a serious crime.
Jackson said Wherry intentionally failed to follow Brinks procedures by not sounding an alarm when he was confronted by an armed man, Campbell, and gave his dispatcher the wrong information about the location of the robbery, delaying the police response and giving Campbell and Stallings time to get away.
Stallings was arrested after the incident but he was released after he helped authorities recover all but $13,000 of the money that was stolen.
Brown said today that Stallings is "an uncharged co-conspirator" who "has been looming throughout the case" but didn't elaborate because Goodman limited testimony about Stallings.
Campbell said, "I'm sorry about what happened to Anthony" and he feels "remorse" about "the situation we were all put in."
Goodman told Campbell, "Sometimes I think you're a half-decent guy and then you start talking and bobbing and weaving."
The judge said Campbell "insulted the intelligence of the Quintero family and the court" during the trial by claiming that he had put his finger on the trigger to get a better hold on the gun and it went off by accident.
Goodman said that as a former Marine, Campbell had to know you don't put your finger on a gun's trigger "until you're ready to use it."
A large group of Quintero's family members and several of his fellow Brinks employees attended the sentencing hearing.
Vickie Orr, Quintero's birth mother, told Campbell, "I hate you."
Marguerita Bonita, who raised Quintero, said she's generally opposed to the death penalty but she thinks Wherry and Campbell "deserve a death date like the one they gave to Jimmy." She said Quintero's nickname was "Jimmy" and his family members called him by that name.
