Chris Dawson has reportedly been arrested in Queensland and is expected to be charged with the murder of his wife, Lyn.
Detective Chief Inspector Chris Olen told The Australian, “A 70-year-old man has been arrested this morning shortly before 8 o’clock in relation to the murder of Lyn Dawson.”

Lyn Dawson went missing from Sydney’s northern beaches in January 1982.
NSW police established a strike force in 2015 to reinvestigate her disappearance.
