Zachary Hebda was diagnosed with leukemia in 1998 at the age of five. He immediately began a course of treatment, including chemotherapy, and in January of 1999, his cancer was in remission. Due to a particular leukemia chromosome, however, Zachary still required a bone marrow transplant. His mother was a donor match, and Zachary underwent the transplant in April of 1999. But despite all treatment efforts, he died on June 19th as the result of an infection.
