Deadly tornados tore through several Oklahoma communities on May 19, 20 and 31, 2013. These are the stories of natural disaster and its aftermath, and of communities healing and recovering.
Seven children were killed at an elementary school in Moore when a massive tornado tore through the area last month.
And the disaster has led to questions about why Oklahoma used previous federal disaster money to build more than 10,000 storm shelters in homes, but only 85 in public schools.
Getting the answer means going back to another major storm, on May 3rd, 1999, and another state.
