Although he had pointed seven crime scenes out to the police, Nyauza claimed that the police had drugged him instead of giving him his HIV medication. Police had recorded Nyauza pointing out the crime scenes, and he showed no visible signs of intoxication, so the judge dismissed his claim. When asked why his semen was found in several of the victims, he claimed that it was because he was a man of exceptional sexual prowess who slept with many women. Although there was only direct evidence against Nyauza in eight of the murders, forensic psychologist Gérard Labuschagne used linkage analysis to argue why all 16 cases had to have been committed by the same offender. On 5 November 2007, Nyauza was found guilty of 16 counts of murder, one count of attempted murder, four counts of rape, and three counts of robbery. He was given 16 life sentences for the murders and an additional 140 years in prison for the rest of his crimes.
