Drug Deal gone awry
It seems the lady IS a real doctor, and she doesn't appear to live in a "bad" neighborhood.
The death scene is obviously torture and evidence coverup.
The doctor looks Asian and her name is unusual to me.
The "Center City" section is very middle/upper-middle class. The term "row house" does not mean "dilapidated slum house". In this context it just means a house that shares common walls with the neighboring house. She was a resident/research fellow, and was likely making good money, but would not be making huge money until after she passed her boards.
Some of those row houses price at the upper six figures - Society Hill.
Just ‘cause she was a doctor doesn’t mean she was very wealthy. Hundreds of thousands in student debt, maybe still in residency. The big bucks don’t kick in right away and under Obamacare, maybe won’t ever.
