Sofia City Court once again postponed the trial for the murder of alleged mobster Milcho Bonev, dubbed Baj Mile, who was killed in 2004.

The trial was postponed, as the heir of one of the killed men did not appear in court. The next hearing will take place on July 7.

Bulgaria's Former Prime Minister and now rightist MP Ivan Kostov, as well as brothers Krassimir and Nikolay Marinov, dubbed the Marguins, alleged underworld bosses and heads of the obsolete SIC grouping that are now in jail, have been summoned as witnesses in the case.

Bonev, one of the founders of Bulgaria's obsolete ex-grouping SIC, and his bodyguards were executed July 30, 2004 in broad daylight in Slavia restaurant-garden in Sofia's Ovcha Kupel district .

Tihomir Dochev, Stilian Georgiev, Georgi Stefanov, and Anatolii Munkov, aka the Rat were arrested on charges of involvement in the gang-style shooting of Bonev and five of his bodyguards. They were also charged with attempts on Alexander Ananiev's and Emil Stoilov's life.

Baj Mile was believed to be an important link in the drug trafficking and distributing network on the Balkans, investigated by Bulgarian and Serbian special services.
