Lore & Background
William Unek, born Adrogo s/o Urwinyo, was an Alur from the Jahoulur chiefdom in Okoro County, West Nile District, Uganda. While living in the Belgian Congo, he killed 22 of his relatives in a mass stabbing during a family reunion in Mahagi territory, believing they had used witchcraft to sabotage his marriage. He fled to Tanganyika Territory, assumed the identity William Unek, and became a police constable under the British administration, serving in Malampaka village, Maswa District, Lake Province.
Reader's Guide
William Unek's significance lies in the scale and brutality of his crimes, which spanned two colonies and exploited colonial administrative gaps. His ability to evade capture after the first massacre, assume a new identity, and join the police force highlights the limited background checks and cross-border coordination of the era. The joint investigation between Congolese and Ugandan authorities that uncovered his true identity underscores the challenges of colonial policing. His case remains a notable example of a serial mass murderer operating across colonial borders, with his motives tied to personal grievances and beliefs in witchcraft.
