Murphy was one of three inmates at Portsmouth Naval Prison in Kittery, Maine, who were unwilling participants in a government-approved experiment. Murphy was the only known survivor of a zombie bite who did not turn into a zombie. His blood contains antibodies that are humankind's last and best hope for a vaccine.
