Chris Dawson, the ex-husband of missing woman Lynette Dawson, has been arrested in connection with her disappearance.
The former high-school teacher, aged 70, was arrested on Wednesday morning in Queensland.
Lynette's disappearance and suspected murder has been the subject of a wildly popular podcast, The Teacher's Pet.
Dawson was taken to Southport Police Station and is expected to be charged, according to 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,' confirmed Detective Chief Inspector Chris Olen.
'He’s been taken to Southport where he will be charged. NSW police will seek an extradition.'
Lynette, a mother-of-two, vanished 37 years ago in January of 1982.
