In this song of Hunger Games [The hanging tree], there's this part that seems odd to me:
Are you coming to the tree, where they strung up a man they say who murdered three.
Why is "Who" used here? Is it a relative pronoun, or something similar?
I believe "who" is used to substitute "a man". However, it sounds very odd to me, since I haven't ever heard something likewise.
However, if "who" is really substituting the noun "man", does that mean I could say:
They didn't like Maria. They said who was not such forthcoming person.
Thank you in advance.
