Abby had been in the City for six weeks after running away from her home with her mother and her mother's new boyfriend in New Pittsburgh. Abby had been born in Tampa, but her mother moved them both to New Pittsburgh. Abby hated her mother's new boyfriend, hence her leaving.
Abby was about five foot six tall.
Abby was at a shelter in the City when Glen Dunbar helped her stop receiving some unwanted attentions from another homeless person. After getting her meal supplement, she left the shelter with Glen to head to another smaller shelter over on Abbot. Glen pricked her with a ring on his hand, which eventually knocked her unconcious. Her 'body' was discovered near the Wall by a routine sweep by a Watch Drone. It was later discovered that the bodies were organic bio-print copies, hence why they were stuffed with straw and it was thought that their organs had been removed.
