Broadway north of SW 149th on Tuesday, May 21, 2013, after a tornado struck south Oklahoma City and Moore, Okla., on Monday. Peterson was walking from his home with a wagon of things he was able to salvage. Peterson, his 2-year-old daughter Ashley and pregnant wife Brandi were in their home when it was destroyed by the tornado. -- AP Photo/The Oklahoman, Nate Billings
