On June 2, 1964, Slivko killed his first victim, a 15-year-old runaway boy named Nikolai Dobryshev. Slivko claimed this particular victim was killed unintentionally, being unable to revive Dobryshev once he was unconscious. He dismembered the boy's body and buried him, also destroying the film and photographs he had taken of this particular victim. In May 1965, Slivko killed his second victim, Aleksei Kovalenko. Slivko began operating a club for boys named "Chergid" in 1966, after his first club had been destroyed in a fire.
