Silent Killer

First kill

I saw him with my own eyes. I saw him kill that girl. Nobody knows. Hi I'm Thomas Clif and things haven't been normal around here lately. I have see the craziest things around her in Helltown but not as bad as this.
Three weeks ago , a girl named Sidney was sitting on her back porch when suddenly a masked man came up from behind her and stabbed her in the neck instantly killing her. Nobody knows how she died but me and I refuse to tell.
I would tell but then I'll be in trouble.
Then a week later a man named Max was found hanging from his balcony with a chain around his neck. Police think they have found evidence on who killed him but I doubt it. See what I mean things are strange around here and it is really frightening.
I am just wondering who is next and who it will be. We need to find answer quick and in a hurry. Before it is too late and nobody finds out who it was.
