This morning at 9:02 Central, Oklahoma City marks the 15th anniversary of the bombing of the Alfred P. Murrah Federal Building.

Timothy McVeigh, an anti-government extremist, killed 168 people that day, including children. "The McVeigh Tapes," a two-hour documentary will air tonight featuring never-released audio interviews with McVeigh, giving you a chance to hear him in his own words and voice.

Bud Welch lost his daughter, Julie Welch, who was just 23, in the Oklahoma City bombing. Welch,

now the president of Murder Victims' Families for Human Rights,

came to oppose the execution of McVeigh because he realized that the killer's death wouldn't help his own family heal.

If you want to hear what forgiveness and wisdom sound like, just listen to him:

"Each time I speak, I'm able to tell stories about Julie and some wonderful things that she did as a child growing up, and her education and such. I kind of keep her alive by doing that. "

“I couldn’t imagine what, if anything,

could bring me comfort or lessen my pain and despair,

but I knew it wasn’t the death penalty.”

Welch notes that neighbors say McVeigh was a good student
and that he returned from the first Gulf War with PTSD.
