William Unek
William Unek was a Belgian Congo police constable and mass murderer, spree killer, and serial killer who killed a total of 57 people in two separate spree killings three years apart. Murder sprees. His first murder spree occurred near Mahagi, Belgian Congo in 1954, where he killed 21 people with an axe, before escaping and finally ending up in British Tanganyika Territory. Apparently because of social misunderstandings with his boss, Unek went on a second rampage which began in the early hours of February 11, 1957. Armed with a stolen police rifle, 50 rounds of ammunition, and an  axe, he started killing people in the area of Malampaka, a village about southeast of Mwanza. Within twelve hours, Unek shot dead ten men, eight women, and eight children, murdered five more men with the axe, stabbed another one, burned two women and a child, and strangled a 15-year-old girl, thus killing a total of 36 people. He then changed out of his police uniform into clothes stolen from one of his victims and fled. Among the dead was reportedly his own wife, whom he killed in their hut before setting it on fire, as well as the  wife of a police sergeant. Manhunt and death. For nine days, Unek was sought by Wasukuma tribesmen, police, and eventually a company of the King's African Rifles in Tanganyika's greatest manhunt up to that time. Despite the extensive search operation, including dogs and aircraft, and a posted reward of $350, Unek eluded his pursuers until he finally showed up at the house of Iyumbu ben Ikumbu, who lived only away from Malampaka, in search for food. When Iyumbu reported the incident to police, he was asked to keep Unek with him and notify them, should the killer  come again to his home. Unek, still armed, reappeared at about 1:00 a.m. the next day. Iyumbu, sending his wife to police, gave Unek food and engaged in a conversation with him for nearly two hours until help arrived. At that point, Iyumbu ran out of his house whereupon a Police Superintendent threw a smoke bomb, setting the house on fire. Unek, severely injured when attempting to evade capture, later succumbed to his wounds in hospital. Iyumbu later received a financial reward of £125, as well as the British Empire Medal for his bravery leading to the capture of  the constable. Aftermath. As response to the murders, a fund was created to help the descendants of those killed and a maternity clinic was built as a memorial for Unek's victims. His rampage ranks among the deadliest of the twentieth century.
