Solution :-
The victim is a famous chemist so if you look at the note very carefully. You will notice that the numbers written corresponding to the atomic numbers on the periodic table of elements.
In Periodic Table, we have following.

The atomic number of Fe is 26.
The atomic number of Li is 3.
The atomic number of Ce is 58.
The atomic number of Ni is 28.
The atomic number of Co is 27.
The atomic number of La is 57.
The atomic number of S is 16.

“Fe(Iron) – Li(Lithium) – Ce(Cerium)” -> Felice
“Ni(Nickel) – Co(Cobalt) – La(Lanthanum) – S(Sulphur)” -> Nicolas

Hence, Felice and Nicolas are the murderers.
