Janine AgainstRevelations

My aunt was killed and I don't know who did it... when I woke up there was blood on the floor falling from her body, the gun was in my hand ... I am extremely confused!
I have to find out what happened, but I can't stand waiting for the police to take care of it, because I'm their number one suspect. Will you help me solve this mystery? To unlock trophies play Gamejolt's Ver.!
