In 2017, three friends brutally murdered family members within just three days of each other.They had no previous convictions and were all good students attending the City College, Manchester.After being arrested, one of the murderers diaries was found and it's contents posed more questions than they answered. Whilst the vast majority believed the friends were involved in a cult, the story was hidden by the authorities and families of the victims for fear of a similar reoccurrence.There are some people that have read that diary and believe that something more sinister was at work during the murders. For the first time, that diary has now been published allowing you to make up your own mind. Notice the changes in writing style as the author's persona changes in the days leading up to the murder.It contains some pretty horrific writings and is not for the faint hearted but may hold the key to the unanswerable question, was a Siren roaming the streets of Manchester in 2017?
