Hundreds gathered at the Oklahoma City National Memorial to honor the 168 lives lost, the survivors and everyone impacted on April 19th, 1995. Twenty-nine years later, we still remember."This place reminds us that those barrels should be buried like toxic waste, and as mayor of this scarred city, I ask you to bring a shovel," Mayor David Holt said. "You can't be passive, you didn't ask for this obligation. It was given to you, but it is ours nonetheless. We must be ambassadors of kindness, peace, love and understanding, emissaries of better conversations." It was a cold morning, but the sacred grounds were packed and the message of unity was delivered. Family members, survivors, first responders and citizens who will never forget that fateful Wednesday morning came to pay tribute. As another remembrance ceremony wrapped, family members paid another visit. "I think it's such a symbol – an empty chair, I mean my goodness. That right there kind of tells everything," said Doris Jones, mother of Carrie Lenz and baby Michael.One by one, flower by flower, the 168 chairs for 168 lives were decorated.A chair in the back row has two names. Jones lost her daughter Carrie, who was pregnant with baby Michael."She was 26. Michael was due in August. So yeah, she was six months pregnant," Jones said. "It's so hard. April 1st comes, and I'm just kind of out of it. I'm just not worth a darn, until the 20th." It was another beautiful ceremony on Friday filled with powerful words from powerful figures. The names of the victims were read out one by one. "I will always be here. Until I can't remember or can't walk, I will be here. Then my son will have to push me in a wheelchair. I will always be here," Jones said. Many families gather to honor loved ones."Every year, it evolves into a different meaning," said Dr. Bonnie Martinez, daughter of Rev. Gilbert Martinez. In the front row, the Martinez family grows with every ceremony. "You can see we have a really big family. We don't always all make it to Thanksgiving, we don't all make it to Christmas, but we all make it to April 19," Bonnie Martinez said. "I have a daughter of my own. I feel like it's more of a celebration now." Her father was at the federal building to help a friend get a Social Security card. "Acknowledging and remembering what my dad left behind, which is a big loving family," Martinez said. "I love seeing how the family has grown, it's always been around the chair." Another year passed and, once again, April 19 serves as a reminder that violence never wins. "I hope people realize that they didn't break us. Actually, they brought us together," Martinez said. "So I carry that with me too."
