He would then convince them to go with him to his home, and after reaching his residence, he would rape them, rob and kill them. However, neighbours say that he may have killed a young man they lived together when he first rented the house. 4. Why didn’t authorities arrest Kazungu earlier? According to Boniface, an elderly resident in a neighborhood where Kazungu lived, the alleged serial killer never allowed people to enter into his home. He said that whenever the local leaders or the landlord came to his residence, he would become distraught and refuse their entry, claiming that he claimed there was a cobra inside the house, which deterred them. But why didn't local authorities act early or did someone sleep on the job? 5. Did he have accomplices? The investigators haven’t revealed if Kazungu had accomplices in the crimes he committed. However, some neighbours believe he might have been helped by some people in certain activities like digging the hole where he buried the victims, considering its depth. According to RIB’s spokesperson Thierry Murangira, the investigators found a pit Kazungu had dug in his kitchen, where he used to bury his victims. 6. Does the suspect have a criminal record? RIB spokesperson Thierry Murangira said Kazungu had been arrested earlier on in July on charges of theft, rape, robbery and use of threats, but was granted bail because there wasn’t enough evidence. According to Emmanuel Nizeyimana, the executive secretary of Busanza cell, Kazungu was apprehended previously under the case of robbing girls money and mobile phones, and it was suspected that he would bring them at his residence and rape them. But no one suspected he had committed murder.
