Oklahoma City mourners on Thursday marked the 12th anniversary of the bombing that killed 168 people by reaching out to victims of the Virginia Tech shootings and victims of violence everywhere. Mourners gather each April 19 at the former site of the Alfred P. Murrah Federal Building to observe the anniversary of the bombing, which injured hundreds. Participants observed 168 seconds of silence, followed by family members reading the names of their lost loved ones. Organizers said attention is also focusing on the killings of 32 people at Virginia Tech by a student who then killed himself on Monday. "Violence obviously is happening," said Nancy Coggins, spokeswoman for the Oklahoma City National Memorial & Museum. "We hope there are ways we can reach out to them and offer support. They will be in our minds and in our hearts."
