Nicholas B. Corwin was an eight-year-old boy murdered by Laurie Dann, a mentally ill woman, in a Winnetka, Illinois elementary school on May 20, 1988. Dann also shot several other students, all of whom survived, then took a family hostage and set a fire in their house before committing suicide. Earlier that day, she had tried to poison several acquaintances and set fires in a school and a daycare.
