Russell Barnaby is a Dead Risingsurvivor. He is an old man central to Brad and Jessie's investigation, and who seems to know more about the true nature of the outbreak than almost anyone else. He is a brilliant but misguided scientist hired by the U.S. government to come up with a way to genetically mass-produce cattle for human consumption. Greedy and narcissistic, his ego seems to always get the best of him. Somewhere along the way during his previous government work, things went horribly wrong. This was quickly covered up by the military, what happened is known only few as the "Santa Cabeza Incident."
