In 2000, the film showing the killings was discovered by Russia's security service on sale in Grozny,
Tamerlan Khasaev The first perpetrator of the massacre identified was Tamerlan Khasaev. At the time Khasaev was already in jail for kidnapping a man in December 2001, and by chance a police officer happened to see the tape and recognized Khasaev from the earlier abduction investigation. Khasaev was brought back to Dagestan from a jail in central Russia to face charges for the death of Alexey Lipatov. In an interview with a Russian investigator, Khasaev said he was simply following orders, and while he described the act as "unpleasant", he expressed no remorse.
Arbi Dandaev Authorities in 2000 identified Arbi Dandaev, accused of executing Vasily Tashkin and Boris Erdneyev. Dandaev evaded capture for eight years but was arrested in
Grozny by Chechen police on 3 April 2008. According to the investigation, Dandaev turned himself in, confessed to the crime, and confirmed his testimony when he was taken to the site of the execution. He pleaded not guilty, however, before the Dagestan Supreme Court, saying that he was
interrogated under duress and refused to testify. Nevertheless, the court found his previous admission of guilt valid because it was made in the presence of a lawyer and no complaints were filed at the time. The court studied the film of the execution, and noted that the name Arbi was clearly pronounced in the recording. In interviews with the residents of Tukhchar village, one claimed to recognize Dandaev, although the court weighed the eyewitness evidence lightly given the villager's advanced age and uncertainty. Dandaev's defense also claimed that Dandaev was mentally disturbed, and petitioned the court multiple times to repeat psychiatric evaluations that previously had determined that the defendant was fit to stand trial. The petition claimed that in 1995, Russian soldiers wounded Dandaev's younger brother in Grozny, and after some time in the military hospital the boy's corpse was returned to the family and his internal organs were harvested to fuel the illegal Chechen
human organ trafficking trade. According to Dandaev's lawyers, the incident caused intense mental trauma, and the charges against Dandaev were devised to prevent the defendant's father from seeking legal redress for the death of his youngest son. Nonetheless, the court held that Dandaev was sane and that the investigation into his brother's death had no bearing on the case. Dandaev was convicted, and although the prosecutor asked for a sentence of 22 years, the court sentenced Dandaev to life imprisonment in 2009.
Rizvan Vagapov On 8 August 2011, Rizvan Vagapov was detained by law enforcement agencies in Grozny. He was convicted and sentenced to 18 years imprisonment for his role in the massacre. ==See also==
