Nothing is known about Mollica's life before the outbreak or as the outbreak began.
After wandering out in his own, The Governor comes across a barn with the names of several people written on it. One of these messages states, "F you Mollica don't come home." The Governor sees another name, Brian Heriot, written several times across the barn, and leaves. (He later adapts this name as his own after meeting the Chambler family.)
