I think it's a strange girl from another universe who somehow connected with him. About that girl: She is a bit strange, lonely and a psychopath, he tried to prove to people that she can see "ghost", but they declared her crazy and diagnosed schizophrenia, after he killed "strange another universe girl" , everyone said it was suicide, but where are the gun and the bullet? ? We don't know that, another strange case that we will watch on YouTube after 02 o'clock at night while the blood freezes in our veins.People gonna make a Wikipedia page where it will be written known for: mysterious suicide / murder.
