Chris Dawson had lost the chance to gather records and eyewitness testimony proving his wife was still alive because he went on trial for her murder 40 years after she disappeared, a court has been told.
The ex-PE teacher is appealing against an August 2022 verdict by Justice Ian Harrison that he killed his wife Lynette Dawson and disposed of her body on January 9, 1982 because he was infatuated with a teenage student.
