The judge in the Chris Dawson murder trial has retired to consider his verdict.
On the final day of submissions in the high-profile trial, the former teachers’ legal team admitted his extra-marital affair with a teenager in the 1980s was inappropriate.
They said this information did not mean Mr Dawson murdered his wife Lynette, who disappeared soon afterwards.
Mr Dawson’s lawyer said the affair provided a motive for Lynette to leave the family home at the time, arguing evidence suggested she was still alive after the date around which Mr Dawson allegedly killed her.
Prosecutors today argued Mr Dawson’s failure to fully disclose his new sexual relationship to police could be treated as a lie by omission.
