This is a research paper, so you must use two research sources: articles on true crime, articles on podcasts, articles on rhetoric, etc–in addition to the two podcast episodes
Whenever you quote or paraphrase those research sources, make sure to provide an in-text citation for them. When quoting or paraphrasing the audio, timestamps are an ideal in-text citation.
Include the following sections in your paper: podcast structure, objectivity, plot, and conclusion. Each section has guiding questions outlined below. You do not have to discuss every single guiding question in each section, but your paper should at minimum, discuss the podcast structure, objectivity, plot–and provide a conclusion that at least touches on the excerpt I provided below.
