Nothing is known about Mr. Spears prior to the outbreak.
Mr. Spears is a member of Zona and has been treated to the experimental vaccine from Murphy's blood. As the treatment fails recipients start to loose brain functions and go crazy. Mr. Spears takes a 4-iron to the head of another inhabitant of Zona, and then starts to practice his golf swing in his underwear. After a brief conversation with Murphy about golf, Mr. Spears is last seen chasing a man down the corridor.
