Mrs Hathersage was a pathologist present at Weatherfield Crown Court in May 2010 as a prosecution witness at the trial of Gail McIntyre for the murder of her husband Joe.
Under cross-examination from Gail's barrister Mr Hughes, he got her to admit that the blow to Joe's head come have come from the swinging boom on his boat, not a blow from a rolling pin as the prosecution alleged, and that this may have caused a weakened state in which Joe would have been unable to drag himself out of the water in Lake Windermere, where he met his death.
