In late 1994, Rjabkov got into an argument with two brothers named Vladimir and Dmitri over debts and women. Angered by their interaction, he decided to kill both, enlisting the help of another acquaintance named Aleksandr Tronin. In early January, he bought a
TT pistol from a friend named Yuri, and on January 15, he and Tronin lured the brothers to a forest near
Kehra. Once there, Rjabkov fired two shots at Dmitri, before proceeding to shoot Vladimir three times, killing both. He and Tronin then hid the bodies. On March 26, together with his 24-year-old brother Deniss and 33-year-old friend Lev Šmõrov, the trio went to the AS Krooning gas station on Paldiski Road in
Tallinn. Deniss acted as the getaway driver, while Rjabkov and Šmõrov went inside, ostensibly to buy cigarettes. They came face-to-face with two clerks, Aivar and Eeno, shooting the former non-fatally while the latter was hit in the heart, dying on the spot. Rjabkov and Šmõrov then stole 1,500
kroon and left. Aivar survived his injuries, but the bullet was left lodged in his spine. His brother and Šmõrov, who both received 9 years imprisonment, appealed their verdicts, with only the latter succeeding in getting a small reduction of one and a half years. ==Release==
