Joyce's Abuse of X

Joyce was found dead in her London apartment on January 25th, 2006. Her remains were so badly decomposed that she had to be identified via dental records. The first person the police wanted to talk to concerning Joyce's death was the mysterious boyfriend of Winter, 2003. But given that no one knew this man's identity, there was no tracking him down. Police then attempted to track down Joyce's abuse of X, but he too seemed to have just dropped off the face of the earth. Yet as one pathologist admitted after, almost two years spent rotting in her apartment, the prospect of murder couldn't be 100% ruled out.
