In 1951, Sathasivam was arrested and accused of murdering his wife Paripoornam Ananda Rajendra, who was found dead at her garage adjacent to the kitchen on 9 October 1951. He was acquitted after a twenty-month sensational trial, having spent twenty-months in
remand prison. He stood trial before a special jury at the
Assizes Court of the Western Province, presided over by Justice
Noel Gratiaen. He was acquitted by a unanimous verdict and three prosecution witnesses (a cab service manager, the driver of the cab and Mrs Sathasivam's legal advisor's son) were sentenced to jail for perjury in addition to the conviction of their servant, 18 year old Hewa Marambage William. Sathasivam's defense team was led by
Dr Colvin R de Silva and since the case had contradictory circumstantial and scientific evidence, the defense flew in renowned forensic pathologist
Sir Sydney Smith from the United Kingdom, to aid in the case. Smith focused on the establishment of time of death based on the frequency of body temperature loss, degree of
rigor mortis and digestion pattern of her stomach and intestine contents. Then he focused on the myriad injuries on the body and the condition of her dress, which contradicted the statement of William. The jury deliberated only a little and acquitted Sathasivam and convicted William. ==Later life==
