Tuesday is the tenth anniversary of the Oklahoma City bombing. 168 people died. Over 500 were injured. Meet Budd Welch, father of Julie Welch, who lost her life that day:

Emmett "Bud" Welch, 65, whose daughter, Julie Marie, died in the blast, has found his own way to deal with the pain. The bombing turned Welch, a former gas station owner, into an international crusader against the death penalty and human rights violations.

Welch has spoken about human rights in London, Rome, Kenya and dozens of other places all over the world. "For 11 months after the bombing, I dealt with my situation by drinking. I'd go to the bomb site two or three times a day, with my head splitting from a hangover," Welch said. "Finally, one day, I said, "What are you doing to change your life?'

"I remembered how Julie was so adamantly opposed to the death penalty. She felt so strongly, she started an Amnesty International chapter in her high school at age 16."
