TUCSON, Ariz. — A sixth man sentenced today for the 2010 killing of border patrol agent Brian Terry.
Heraclio Osorio-Arellanes will spend life in prison.
Two guns found at the crime scene were traced back to the botched federal program known as "Fast and Furious."
That program allowed criminals to buy guns from U.S. agents with the goal to track them.
Terry's family has been outspoken about their criticism of "Fast and Furious."
KGUN 9 spoke to Terry's sister by phone. Michelle Balogh said Brian will always be the family's hero.
"Oh my god," Balogh said. "Brian is the hero to our children. We just feel bad because Brian was their favorite. He was all about his neices and nephews. He's missing out on births and graduations and weddings and he's just missing out on everything and it hurts."
The last of the suspects in his killing is serving a six-year setence in Mexico for illegal gun trafficking.
The family plans to return to Tucson again, when that man stands trial in the United States.
