William Unek
Ugandan serial mass murderer who killed 58 in two sprees.
William Unek, who died on 20 February 1957, was a Ugandan who committed two mass killings in the mid-1950s, killing 58 people in total. His first attack took place in the Belgian Congo (now the Democratic Republic of Congo), where he stabbed 22 relatives to death during a family gathering in Mahagi territory. He believed they had used witchcraft to ruin his marriage. After escaping from Belgian authorities, he fled to Tanganyika (now Tanzania), assumed a false identity, and joined the local police force as a constable under British rule. About two years later, convinced that his new partner was cheating on him with his supervisor, he carried out a second rampage in and around Malampaka village, using a gun and an axe to kill 36 people. A nine-day search ended when William was shot and mortally wounded during his arrest.

Lore & Background
William Unek's birth name was Adrogo s/o Urwinyo, an Alur of the Jahoulur chiefdom in Okoro County, West Nile District. On a Saturday night in either February 1954 or mid-1955, Adrogo invited 22 family members to a banquet at his home in Angala village, Angal chiefdom, Mahagi territory, near the northern Congo–Uganda border. After the celebration, 20 relatives went to sleep while two children went outside to play. Adrogo used a machete to kill each of the sleeping guests, then set the home on fire and fled, encountering the two children and murdering them as well. He obtained a boat at Lake Albert to cross into Uganda. According to Belgian Congo authorities, Adrogo blamed close relatives for infertility during his second marriage, accusing them of 'hexes'. He was described as showing signs of neurasthenia. He eventually ended up in Tanganyika Territory, where he gave the false identity William Unek and claimed to be Acholi. By 1956, William had joined the Tanganyika Police Force as an askari, holding the lowest rank of constable. He was stationed to Lake Province, residing in Malampaka village, Maswa District. William, along with his concubine Angelina, lived behind the police post. He was described as 'always quiet and reserved'.

On the night of 10–11 February 1957, William committed a second spree killing. Just after midnight, he came into the Malampaka police post and asked two superior officers, Sergeant Clement and Corporal Opiyo, to accompany him to arrest 'a man with several diamonds'. During the trek, William struck Opiyo in the back of the head, causing him to lose consciousness. Opiyo later found Clement dead in a hedge. William broke into the police armoury using an axe, stealing six rifles and 50 rounds of .303 ammunition. He set fire to the hut where he and Angelina lived, and inside the burned bodies of two women and a child were recovered. At Opiyo's residence, the corporal's wife and three children were found shot dead. William shot various people in town, reportedly burning down a second hut, then changed out of his police uniform into clothes stolen from a victim and fled. The killings took place over less than twelve hours. On the night of 12 February, William strangled a 15-year-old girl. Between 14 and 16 February, he attacked isolated homes, killing four more people by gunshots or slashes. The final fatality count was 36. According to William's later testimony, he had developed a one-sided rivalry with Clement, whom he accused of having an affair with Angelina. Following a nine-day manhunt, William was fatally wounded during his capture. His true identity and connection to the earlier murders in the Congo were discovered a month later.
