Garcia says the crimes happened in Lake Worth, North Carolina, 200 miles from Raleigh in the mountains. There is no place by that name. Fictional TV shows often contain fictional locations especially if there is a concern that the plot might negatively impact a real town.
The fictional college, NCC, which Angela and Marcy supposedly go to, does not exist in North Carolina. Garcia identifies the school as "North Carolina College" in the second act. Fictional TV shows often contain fictional locations, including colleges, especially if there is a concern that the plot might negatively impact a real college.
While in Angela's hospital room just before she arrests, a monitor shows a seemingly changing brain scan. Angela would have to be in a CT scanner for those images to be taken, not just laying in a hospital room.
At the beginning, the location states that they are in Washington County, at the hospital. However, later, the door at the police station says "Nash County Sheriff's Office." Nash County is about an hour and a half west of Washington County, closer to Raleigh, while Washington County is closer to the coast.
