Chemical deduction (Posted on 2019-05-13) Difficulty: 1 of 5
A famous chemist was murdered in his own lab. There was no evidence except for a piece of paper with the names of chemical substances on it: carbon, oxygen, nickel, lanthanum, and sulfur. On the day he was murdered, the chemist had only 3 visitors: his wife Mary, his nephew Nicolas, and his friend Johnathan.

The police arrested the murderer right away. Who was it?
