Unsolved Crime Scenes No One Can Explain

44-year-old Danny Casolaro was a freelance journalist. He died in 1991. He was found dead by a member of the hotel's cleaning staff in West Virginia. He had been staying at the Sheraton Hotel. his wrist had been sliced numerous times. Due to the presence of a suicide note, people were quickly believing it was suicide. Reports from the scene said that there was no trauma to the body so that indicated there was no struggle. Also in the bathroom, there was a corked bottle of red wine, a broken wine glass, an empty can of beer, a paper hotel glass coaster, and two white trash bags. There was also a single-edged razor blade at the bottom of the bathtub, indicating he was taking a bath before he died. Now here's the weird part. Casolaro's brother came forth and said that they had a conversation two weeks before and Casolaro warned: If anything happens to me, don't believe it was an accident." He had spoken of many threats over the past couple of months before he died. He kept mentioning the "octopus", a network of individuals and institutions that he beliebved had secretly masterminded a series of scandals. No one had ever been charged with the murder of Casolaro. Also "The Octopus" have never been exposed. 

Do you think it was suicide or a murder cover up?
