Police searches by government and financial institutions failed to prove Lynette Dawson was alive 17 years after she disappeared from her marital home, a court has heard.
Giving evidence at the murder trial of Christopher Michael Dawson on Friday, former detective Damian Loone said police conducted life checks through bank accounts, Medicare, Social Security and Australian Taxation Office in 1999 and again in 2001.
“What was your belief as to whether or not there were government records that indicated Lynette Dawson née Simms was alive?” asked Crown Attorney Craig Everson SC.
“There were no government records,” Mr Loone replied.
The former police officer was involved in the investigation into Ms Dawson’s disappearance in the late 1990s and early 2000s before a second inquest in 2003.
Dawson, now 73, is accused of killing his wife and disposing of her body in January 1982 so he could have an unfettered relationship with a woman, known as JC, who was his babysitter and a student at the high school where he taught.
Although Ms Dawson’s body was never found, Mr Loone said he conducted the investigation as a potential homicide rather than a missing person.
He said conversations with Ray Butlin, whose wife said she saw Ms Dawson at a fruit stall in Kulnara, north of Sydney, failed to change his mind about it.
However, he didn’t think any evidence to suggest she was alive and well was a waste of time and not worth pursuing.
He admitted a psychic was brought to the Dawsons’ home in Bayview and one of Ms Dawson’s daughters was hypnotized during the investigation, but said it led nowhere.
The NSW Supreme Court trial continues.
