Y is the murderer

assume X is saying the truth i.e Y is the murderer

Y says Z is murderer which is a false statement

Z says X&Y aren't the murderers which is also false.

assume Y is saying the truth i.e Z is the murderer

then X & Z are also telling the truth.

assume Z is saying the truth i.e X & Y aren't murderers i.e Z is the murderer
