Chicago Department of Animal Care and Control

The Chicago Department of Animal Care and Control is an investigative source in the Chicago serial-murder inquiry: its reports reveal a concentration of animal-related cases in West Pullman, which Zoe Bentley interprets as a possible early trace of the killer’s plans. The department itself is not shown conducting the murder investigation; its significance lies in the records Lieutenant Martinez brings to the task force and the questions those records raise.

Records and Geographic Pattern

Lieutenant Martinez gives Zoe Bentley a list of reports covering July 2014 through March 2016. The list contains twenty-seven cases, all from West Pullman, a neighborhood in southern Chicago. The concentration supplies the investigation with a specific geographic pattern rather than a general impression of animal-related activity across the city.

The reports do not establish that the same person was responsible for every case. Nor do they, by themselves, explain why the cases occurred in West Pullman. Their value is as a lead that can be checked against other evidence and against what pet owners remember.

The Taxidermy Hypothesis

Zoe notices that the first six cases involved taxidermy. She proposes that the killer may initially have intended to taxidermy human victims, then changed his approach. This is her interpretation of the sequence in the records, not a conclusion confirmed by the department’s reports.

The distinction matters to the investigation: the animal cases suggest a possible line of development in the killer’s methods, while leaving open why that method changed. The records prompt a question about the killer’s earlier intentions; they do not answer it.

Follow-up and Investigative Significance

When Zoe asks whether anyone saw who took the pets, Lieutenant Martinez says the reports contain no such accounts. Scott and Mel Parks have begun contacting owners to verify the information and ask whether they witnessed anything. The interviews are therefore a necessary check on the paperwork, not a result already established by it.

Zoe also reasons that the killer had been less careful about discarding animal remains than about disposing of human victims, and suggests that he may have lived in or once used West Pullman. The location pattern makes that possibility worth examining, but it does not prove where he lived. In the novel, the department’s records matter because apparently separate animal cases can be read as potential traces of a human murder investigation—provided investigators test the connection rather than mistake a promising pattern for confirmation.
