Other than that Richards serves on the police force for the Los Angeles Police Department, nothing is known about Richards' life before the apocalypse.
Officer Richards is stationed at the Paul R. Williams High School on guard duty alongside Officer Finley, first seen when Principal Art Costa questions a bus driver outside the school on the number of students arriving at school due to an unknown virus spreading. He is then later seen assisting the dismissal of students from the school.
As the city of Los Angeles quickly fell to the undead, Officer Richards' fate remains unclear. It is unknown whether he was able to survive the outbreak or was killed and/or turned into a zombie.
