Who are the killers?

Are you good at solving mysteries? Well, here’s one for you. A famous chemist was found murdered in his kitchen today. Police came and now have six suspects. If it was a two-man job as they think, who do you think it could be? Is this enough information? Well, if you need more, here goes. There was a note next to the body. Written on it was this “26-3-58/28-27-57-16.” Is that enough to solve it?

Give up? Well, remember that the person murdered was a chemist. Chemists are very involved with elements and that brings us to the periodic table. Remember that thing you had to memorize in high school chemistry? If you use that table and the numbers in the note, you will find the answer to be Felice/Nicholas.
