Chris Dawson has lodged the paperwork to begin the process of overturning his guilty conviction for the murder of his wife Lynette 40 years ago.

The 74-year-old has spent the last five weeks in Sydney’s Silverwater Jail, as he awaits his sentencing day in court on November 11.

Despite the high-profile case producing a guilty verdict, Dawson has always maintained his innocence over the disappearance of Lynette, whose body still hasn’t been found.

Sources told Daily Mail Australia last month that Dawson’s legal team had recently lodged a notice of intention to appeal with the NSW Court of Criminal Appeal.

Nine News also reported on Tuesday night the paperwork flagging Dawson’s intention to appeal his conviction has now been formally submitted, as the network prepares to air an interview with one of his daughters.

Shanelle Dawson is preparing to open up about growing up without her mother, along with the torment and confusion that arose form her disappearance in a tell-all interview with 60 Minutes.

Shanelle, who was just four years old when her mum Lynette vanished in 1982, said she was always told by her father that her mother left because she didn’t love her and her other sisters.

“I feel a lot of rage and anger towards him,” Shanelle says in the 60 Minutes preview.

“It was manipulative and gaslighting us.”

“Whatever he said or threatened me kept me quiet for the next 40 years.”
