NEW South Wales Police have concluded their forensic investigation and search of Lynette Dawson’s former home.

In a press release, the NSW Police said they did not find Lynette’s remains or any items relevant to the investigation at the northern beaches property.

The operation is part of an investigation into the 1982 disappearance and suspected murder of Ms Dawson.

The operation started Wednesday September 12 and Strike Force Scriven was established by the Homicide Squad’s Unsolved Homicide Unit in 2015 hoping to provide answers for Ms Dawson’s family.

“We want to make sure that we can put this to bed,” Homicide Squad commander Detective Superintendent Scott Cook told reporters last Wednesday.

Police began to “hand dig” at the Dawson’s former home in Sydney’s northern beaches on Wednesday.

Contractors will remain on the property to restore and repair the any areas that may have been affected by the police investigation.

Lynette Dawson’s disappearance has attracted interest not only in Australia but around the world due to The Australian’spopular investigative podcast The Teacher’s Pet.

Although no remains have been found, but Ms Dawson’s pink cardigan was recovered and was found to have cut marks consistent with stab marks.

Despite two coronial inquiries in 2001 and 2003, no one has been convicted of the murder, but former husband Christopher Dawson has long been a suspect in the case.

Mr Dawson has maintained his innocence and consistently denied having a hand in his wife’s disappearance.

In 1982 Mr Dawson claimed his wife ran off to join a religious cult.

However, Det Supt Scott Cook said he had “absolute” confidence police would be able to lay charges against Mr Dawson, even if the operation didn’t find the remains.
