In a post to the Official Oli Herbert Page on Facebook, the cause of death for the late All That Remains guitarist Oli Herbert has been revealed. Herbert passed away from drowning. He also had anti-depressants in his system that he was not prescribed for or under treatment for. As a result of this news, the family has decided to cancel the public memorial that was to be held at the Worcester Palladium, tomorrow, November 11th. Herbert’s family is also asking for help and leads here.
