Russian federal investigators say three suspects arrested in connection with the murder of a high-ranking police officer and five of his relatives have confessed to the killings.
The investigators identified the arrested men on May 3 as Roman Fataliyev, Islam Babayev, and Orxan Zahrabov, all natives of Azerbaijan.
On May 2, Russia's Investigative Committee said the suspects were from Central Asia.
Investigators said on May 3 that a fourth suspect, an ethnic Tajik named Mahmadali Ahmadov, was still being sought.
Tajik Interior Ministry spokesman Jaloliddin Sadriddinov told RFE/RL that if Ahmadov was a Tajik citizen currently in Tajikistan, Dushanbe would not be able to extradite him to Russia because Tajik laws do not allow the extradition of the country's own citizens.
The deputy chief of staff of the Samara region's interior department, Andrei Gosht, was found dead at his home in Syzran on April 24 along with five of his relatives.
