Task: Question Answering
Input (English): Context_1 : Matti Haapoja (September 16, 1845, Isokyrö – January 8, 1895, Turku) was a Finnish serial killer who was much covered by the press at the time of the murders. The exact number of his victims is unknown. He was convicted of two murders and was scheduled for a trial for his third murder trial when he committed suicide in his cell. He can be linked to seven other identified murder cases, but most of those happened during his exile in Siberia and are poorly documented, so his involvement is not certain. It is claimed that he confessed to 18 murders, but there are no details about this supposed confession, and the figure should be regarded as unreliable. Some sources estimate his total number of murders as 22–25. He also non-fatally wounded at least six men in knife fights. Context_2 : Andrei Romanovich Chikatilo (Russian: Андрей Романович Чикатило , Ukrainian: Андрій Романович Чикатило ; 16 October 1936 – 14 February 1994) was a Soviet serial killer, nicknamed the Butcher of Rostov, the Red Ripper, and the Rostov Ripper, who committed the sexual assault, murder, and mutilation of at least 52 women and children between 1978 and 1990 in the Russian SFSR, the Ukrainian SSR and the Uzbek SSR.

A child rapist and cannibal, he boasted that he "had children in every state", and at one time stated the number was about 100. However, it is not known whether he was referring to rapes or cannibalization, nor is it known if the statement was truthful. He was a suspect in at least five murders during his lifetime. Fish confessed to three murders that police were able to trace to a known homicide, and he confessed to stabbing at least two other people. He was put on trial for the kidnapping and murder of Grace Budd, and was convicted and executed by electric chair. His crimes were dramatised in the 2007 film "The Gray Man", starring Patrick Bauchau as Fish.
