He said: “It was not until December that I had any concerns about Joel. “We were aware of the risks of him being vulnerable and I emailed Ms Goodwin with my concerns. “But Joel was also looking forward to Christmas. He did not seem to be on the verge of a psychotic relapse.” Ms Goodwin, who saw Joel regularly, said there had been no evidence of anyone staying with him in his flat and no evidence of “cuckooing” - where drug dealers use the home of vulnerable people for criminal activity. At 2.40am on December 21, another resident in the block of flats called police and reported their friend had “gone crazy”. Officers attended and found the window in the front door of the building smashed with blood on, and a lot of blood in Joel’s flat.
