Kathy is a receptionist at Fletcher-Greene. She is married to Michael.
Before the infection, Kathy was married to Michael and got a job at Fletcher-Greene.
On the day of the outbreak, Kathy went outside to smoke. While outside, she was bitten by a werewolf, and Michael brought her back inside. After locking her in a storage closet, Michael, Duncan, Stan, Rosie, and Pedro tried to convince the others in the group to keep her alive. Midway through Michael's plea, a transformed Kathy broke out of the closet and killed him. Stan then decapitated her by chopping her neck several times with a silver knife from the kitchen. Both were later buried outside the office building.
After Kathy transformed and killed Michael, Stan decapitated her.
