Correct.Liberty Island, Statue of Liberty
I've got another one.
George, who owns a chemical factory, decided to murder his wife. To hid his crime, he attempted to destroy her body by dissolving it in a vat of concentrated acid. His wife's body and clothing completely disintegrated, but the authorities were nonetheless able to find evidence of her presence in the vat.
Why didn't George's plan work and what evidence did authorities find?
