Sofia City Court has declared not guilty of unlawful drugs and weapons possession the alleged Bulgarian mafia boss Yosif Yosifov aka Yosko.

During a search of Yosifov’s home in Sofia, warranted as part of an investigation into a high-profile contract murder, police found a metal briefcase with nine millimeter bullets, two guns, marijuana and 16 pellets of heroin.

Meanwhile Yosifov has been found guilty of causing the deaths of two people in a hellish car crash last year.

On March 2, 2011 Yosifov caused a car accident in the capital Sofia's affluent Boyana suburb, killing two and sending three to the hospital with serious injuries. A head-on collision took place between his armored Mercedes SUV and a Kia van with Blagoevgrad tags.

Yosifov, 42, has a long rap sheet for a variety of crimes. He was one of the defendants in the high-profile kidnap case of a Croatian citizen from a night club in the western town of Slivnitsa. Yosifov was sentenced to two years behind bars, but later released on appeal.

Yosko's group has been linked to some of Bulgaria's top high-profile contract murders, including the one of notorious mafia boss Konstantin Dimitrov, aka Kosyo Samokovetsa, who was shot in Amsterdam back in 2003.
