Andrei Chikatilo
Andrei Romanovich Chikatilo (Russian: Андрей Романович Чикатило; Ukrainian: Андрій Романович Чикатило, romanized: Andrii Romanovych Chykatylo; 16 October 1936 – 14 February 1994) was a Ukrainian-born Soviet serial killer nicknamed "the Butcher of Rostov", "the Rostov Ripper", and "the Red Ripper" who sexually assaulted, murdered, and mutilated at least fifty-two women and children between 1978 and 1990 in the Russian SFSR, the Ukrainian SSR, and the Uzbek SSR. Chikatilo confessed to fifty-six murders; he was tried for fifty-three murders in April 1992. He was convicted and sentenced to death for fifty-two of these murders in October 1992, although the Supreme Court of Russia ruled in 1993 that insufficient evidence existed to prove his guilt in nine of those killings.
