The fathers of a camper and a counselor who were killed during last year's deadly floods at Camp Mystic in Texas said they'll keep advocating for improved summer camp safety to help prevent other families from experiencing a similar tragedy. Saturday, July 4, marks one year since the catastrophic floods killed more than 130 people, including 25 girls and two teenage counselors at the all-girls private Christian camp in Hunt, Texas. Matthew Childress' 18-year-old daughter, Chloe, and Ryan DeWitt's 9-year-old daughter, Molly, were in the same cabin when they died in the floods. That night now connects the two fathers - forever. We all began to be driven by understanding the truth. What happened that night? What happened leading up to that night? What happened following that night? Childress told CBS Mornings. At that time, even though I knew it was irrational, I felt that if I could put that timeline together, that I could save my daughter, that I could save these girls, he added. Childress, DeWitt and other families of the victims have since helped drive legislative changes regarding camp safety nationwide. They've also sued the camp, accusing its owners of gross negligence. These young girls died because a for-profit camp put profit over safety, their lawsuit alleges. The camp is not the only entity being blamed, with the tragedy being attributed to multiple missteps, including that communities did not have outdoor warning sirens in much of the affected area. Push to change camp safety laws Investigators who looked into the camp's evacuation response during the floods concluded in a state report - released last month - that the camp did not prepare for the storm or have a plan to evacuate. It also faulted Kerr County officials, saying alerts and warnings issued by Texas' emergency management division were disregarded, and that county officials were substantially absent from duty and failed to effectively coordinate with summer camps before the storm. Childress said the families could physically feel the weight on our shoulders being lifted, that that truth was being t #cbsnews #crimewatchdallas
