This aspect of Calvi's death was the focus of the theory that he was murdered, and is this version of events depicted in Giuseppe Ferrara's film reconstruction of the event. In September 2003, the City of London Police re-opened their investigation as a murder inquiry. More evidence arose, revealing that Calvi stayed in a flat in Chelsea Cloisters just prior to his death. Sergio Vaccari was a small-time drug dealer who had stayed in the same flat, and he was found dead in possession of masonic papers displaying member names of P2. The murders of both Calvi and Vaccari involved bricks stuffed in clothing, correlating the two deaths and confirming Calvi's ties to the lodge.
