I read this in college. It's about a family that takes a trip. The car breaks down and 3 men show up and they end up killing the family. I think the grandmother survives.
I had to do a research paper on the symbolism on this story.

Been trying to find it for a couple months now. Please help

Flannery O'Connor's "A Good Man is Hard to Find"

Try r.l.stine
Hope that helped :)
