Joanna Glynn QC acted for the prosecution in a case in which it was alleged that Simon Hathaway lost his temper and shook his five week old son, causing a brain damage from which he died 90 minutes later. It was also alleged that the child’s mother, Anne Hathaway waited 40 minutes before calling 999 to get help. Both defendants challenged expert evidence from a number of disciplines which was relied on by the prosecution to prove their case. The trial concluded on the 7th March and Simon Hathaway was convicted of manslaughter and sentenced to six and a half years imprisonment.
