Bonjour je dois faire une histoire de détective ou il peut être l'auteur ,le temoin ,etc...mais je n'ai pas d'inspiration pouvez vous m'aider. ..merci d'avance

Yesterday Miss elizabeth ,my neighbour got murdered and the police came to find the murderer . I was hidden behind a pillar when an Inspector saw me "Hey who are you " he asked "i'm Emma ,Miss Elizabeth's neighbour " i replied nervously "what are you doing here , don't you know it's the crime scene" he yelled at me  "i was there when that guy murdered her" i said "what , you mean you know who killed her" he asked curiously . Then i told him the whole story "i was coming back from mall when i heard some weird voices from Miss Elizabeth's house ,it seemed like someone was fighting . I went to see what's happening and i saw a guy who shot her in the head and fled. I couldn't see his face because it was dark and he was wearing a mask. I ran quickly to my house because i was really scared.That's all i know" The Police man listened to me carefully and he added "Thank you so much for helping us it would be easy to find the real culprit you may go now " Then i left .
