Hello! I would say the narrator is insane because he can still hear the old man’s heart thumping from underneath the floorboards even after he killed him. His guilt gets the better of him and he turns himself in to the cops. I don’t have any evidence sense I don’t have the story on me, but use something from the story along the lines where he “hears” the thumping of his heart as evidence.
Hi. First, you have used the wrong spelling of, "which". A witch is a character ;)
Okay, back to your question. One example of a flashback in the story, "Borders" is when the mom talks about driving to Salt Lake City to visit her daughter.
If you read the story, you might find some other examples. Hope this helps.
Take care,
Diana
