John Burdick, 30, was at his home at 1442 S. Broadway in Edmond, where he had gone to meet the repairman who was working on his heater. He said they heard a report of a tornado at Covell and Kelly, but that was about a mile from his house so they kept working. He heard the sirens, he said, "but they go off all the time." About two minutes after he heard the tornado was at Covell and Kelly, he said, the back door blew open. He ran to try to keep the door shut. Then he heard a loud bang, which he later learned was a small chunk of his roof being torn off. At 5 p.m., Burdick said, his children were still locked down at school and his wife was at work. He was outside surveying the damage, which included downed electrical wires and the destruction of a barn, a mobile home and a house, all within view from his yard. He had no electricity, he said.
