Peter Washington is a member of Philadelphia's SWAT when the walking dead crisis has reached critical condition. He is a tall African American and is athletic and of considerable strength, agility and stamina. Because he saves the life of a fellow SWAT member of another squad, he is offered a ride out of Philly and so joins the party that goes on to besiege the Monroeville Hyper-Mall. It is suggested at the beginning that he has no qualms about killing a fellow man if other lives are at stake and it is this tension that he carries as the group falls into disarray, leaving him the strongest member but with unclear agendas beyond survival!
