MOSCOW, August 10 (RAPSI) - The prosecutor has requested a life sentence for Makhachkala ex-mayor Said Amirov currently charged with the murder of a department head at the local branch of the Russian Investigative Committee and several other crimes, RIA Novosti reported on Monday.

The prosecutor claims that the defendant’s guilt in all the crimes “is beyond doubt.”

He requests a similar punishment for Amirov’s nephew, Yusup Dzhaparov, and another defendant, Magomed Akhmedov.

The prosecutor requests nine years in a penal colony for each of the other two Akhmedov brothers, 13 years for Murad Aliyev, 20 years for Magomed Kadiyev and 12 years for Zubair Mutayev.

Amirov pleads not guilty and claims the witnesses in the case testified under the harrow.

The defendants in the trial include Amirov, his nephew Yusup Dzhaparov, Murad Aliyev, three Akhmedov brothers, Magomed Kadiyev and Zubair Mutayev. Their alleged crimes include the murder of Arsen Gadzhibekov, acting head of investigation at the Russian Investigative Committee’s office in the Sovetsky district of Makhachkala, in 2011, and plotting and carrying out a terrorist attack at the Moskva mall and entertainment center in Kaspiisk.

Gadzhibekov worked on a number of high-profile criminal cases, including the 2010 twin bombings in Kizlyar, a town on the border with Chechnya, which killed 10 and injured 270. He was also investigating misconduct allegations against members of the Makhachkala city administration headed by Amirov, according to Investigative Committee spokesman Vladimir Markin.

Earlier, the court sentenced Amirov and Dzhaparov to 10 and 8.5 years in prison respectively for plotting a murder attempt on Sagid Murtazaliyev, Head of the Pension Fund in Dagestan and a prominent Russian wrestler whose plane was supposed to be shot down by a mobile surface-to-air missile system.
