could not remember what he did with her body. Guider's statements about Knight over the years were contradictory. Initially he said he could remember nothing about what he did with her. Later he said he had buried her in Cooper Park, in the Sydney suburb of Bellevue Hill, but had dug her up later and put her in a skip at the Royal Sydney Yacht Squadron, Kirribilli, where he had worked as a gardener at the time. In March 2003, he told police he had buried Knight in the grounds of the Royal Sydney Yacht Squadron.

The chief suspect was Brian James Fitzpatrick, who had done time in prison for indecent assault. Fitzpatrick died in a car crash just weeks before he was due to appear at an inquest into Aitken's death. By 2006, Hofman suspected that Guider may have been involved in Aitken's disappearance. At the time, Guider was working just two hour's drive from Narooma, in a Canberra suburb. His mug shot was identified by a member of the Aitken family and an important witness in the case. He had clippings about Aitken in his scrapbook on missing children, and these clippings came from local papers in Narooma, which implied that he had been in the area. However, police considered that there was insufficient evidence to make it worth following up on Hofman's theory. Hofman drew the attention of police to a sketch by Guider, which depicted a girl with a strong resemblance to Aitken. Police viewed the sketch but there were no
