The prosecution opened their case with the jury being taken to the various sites around Adelaide that were important in the trial, and over the first week they called various witnesses to the stand. Kelvin's parents, girlfriend and best friend were called to testify that Kelvin was an average 15-year-old who would not willingly get into a car with a stranger, was heterosexual with no homosexual or bisexual tendencies, and that he had been wearing the dog collar as a joke.
