Maylene Sorrels is a single mom of 10 children, eight of whom still live with her. She is also a teacher's aide at Plaza Towers Elementary School in Moore, Oklahoma. As the tornado hit, Sorrels says she covered her bodies over several children and sang as loudly as she could in their ears as debris flew all around them, including a car. She stayed with the children until their parents came to pick them up, then went to the hospital to get treated for a concussion.
Sorrels' house was destroyed and she has been staying with relatives. If you could like to help Maylene Sorrels and her children, a donation page has been set up for them at fundrazr.com.
