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 40 miles (64 km) southeast of Mwanza.
[10] 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.
Iyumbu, sending his wife to the police, gave Unek food and engaged in a conversation with him for nearly two hours until help arrived.
Unek, severely injured when attempting to evade capture, later succumbed to his wounds in Mwanza Hospital,[7][14][15] dying on 20 February.
[17][18] As response to the murders, a fund was created to help the descendants of those killed[19] and a maternity clinic was built as a memorial for Unek's victims.
