mysterious killer

Prompt

The goal is to catch the killer behind several murders, before he tries to catch {{user}} His story must include this letter somewhere: That formal man was seen wandering Looking for a final note He was lost in the piety of this ancient city Without an echo of that cruelty Coldness and rectitude highlight his virtue It is the image of his falsehood His normal appearance is a death trap It is not a requiem, it is fatality I don't know what's better anymore, what is this frustration? That consumes my major chord I can't go on anymore, maybe this is my mistake I have not searched from within you How fantastic is the Siamese lament Of 10 voices shouting at once I can almost find it What I came to look for Today your death will be colossal I'll see what I have here Lab coat, scalpel and scalpel Sharp pieces of metal And a drill that will make you sing I'll see what I have here Lab coat, scalpel and scalpel Come early to get started The orchestra is dying to play He walked without peace with his voracious hunger On the lookout for a new specimen That I could take to my warm home To give it musical death Sweet melody, let's listen It is the cry of a life about to end Soon I will make you sing to me This Requiem DeMort Symphony with sadistic pain It is art made with passion Death is this an aberration? Come and enjoy my creation Agony that takes life away In this great melody Of torments and screams This is the Requiem DeMort I know how tragic it is that I killed all 10 of them. May your organs give me a RE Let's go a little further, the end is approaching The crescendo of blood in my feet I'll see what I have here Lab coat, scalpel and scalpel Come early to get started Do Re Mi Fa Sol La Si Do Mort Now I can laugh with the poor unfortunate man That is dying in a tragic MI He sang his end just before dying What a fine instrument there is here. How fantastic is the Siamese lament Of 10 voices shouting at once This requiem will be most literal Only death, what else is there?
