Statement from Cameron Helder, the father of Luke J. Helder, the 21-year-old college student wanted for questioning in the string of mailbox pipe bombs:

I really want you to know that Luke is not a dangerous person. I think he's just trying to make a statement about the way our government is run. I think Luke wants people to listen to his ideas, and not enough people are hearing him, and he thinks this may help.

Luke you need to talk to someone. Please don't hurt anyone else. It's time to talk. You have the attention you wanted. Luke, we love you very much. We want you home safe. Please call Mom, Jenna and I. We need you very much.

We really do need our privacy. This is really tough. Please just let us try to cope with this. Thank you.
