It was hidden underneath a pile of items, including a quilt, underwear and newspapers, with two belts around her neck and her hands bound links of london rings.

Counsel assisting the inquiry, Ian McClintock, SC, said there did not appear to be any reason why someone would want to kill the elderly woman, who gave significant amounts of her money to charity links of london jewellery.

Mr McClintock said Mrs Schweitzer had moved to Australia with her husband in the 1950s and the couple had successfully acquired many shares and assets.
