The British newspaper "The Times" has reported that the prime suspect is an Italian named Francesco Gullino (or Giullino) who was last known to be living in Denmark. A British documentary, "The Umbrella Assassin" (2006), interviewed people associated with the case in Bulgaria, Britain, Denmark and America, and revealed that Gullino is alive and well, and still travelling freely throughout Europe. There were reports in June 2008 that Scotland Yard had renewed its interest in the case. Detectives were sent to Bulgaria and requests were made to interview relevant individuals.
