Yuri Leonidovich Tsiuman (born January 30, 1969), known as The Black Tights Killer ("Черноколготочник", transliteration "Chernokolgotochnik"), and The Night Guest, is a Soviet serial killer. All of his victims are reported to have worn pantyhoses. This article of clothing became known as the killer's "calling card." Biography Tsiuman was born on January 30, 1969, in the city of Taganrog, Russia. He had a difficult childhood: his parents were chronic alcoholics who constantly beat him and even threatened to kill him, something for which his father was repeatedly tried for. When his father became seriously ill and died in one of the family's rooms, instead of going to the police his mother began instead to bring in lovers and have sex with them, all in front of her son. During his childhood, Tsiuman was practically speechless with his peers, and was considered a quiet and calm character. He always sat on the bench at the entrance of his grandmother's house and was instructed to roll children in wheelchairs around the yard. As an adult, he was considered an intelligent person and had a passion for thriller films (for watching new films, he used cable TV), was an alcoholic, and had significant issues in talking with women, an illness called Hypoactive sexual desire disorder. Tsiuman's first murder was committed in 1986 on December 24-25th. He had attacked a 16 [some say 17] year-old school girl named Maria during the night and had taken her hostage. At first, she resisted, but later gave in and suggested that Tsiuman go to her apartment, all in the hope that there was somebody there to save her. Unfortunately, here was nobody home. In the apartment, Tsiuman tied her up, beat, raped and strangled her (or rather, tried to strangle her). Before leaving the apartment, he robbed and set fire to the girl's property and room. Further information about the fate of Tsiuman's first victim differs between sources: in one source it is said that the arson failed and the girl survived; in the other, that she died. From 1987 to 1989 there were no murders due to Tsiuman's enlistment in the Russian army and served on the missile forces team. In late June 1989, he committed a new attack on another girl and attempted to beat and rape her, again late at night. After having accosted her and forcibly violating her unsuccessfully, he took her to
