This episode examines the initial theories about how Norma died and the theories that were dismissed. A number of letters were sent from the public to police with a variety of hypotheses about the ‘who’, ‘how’ and ‘why’. Forensic Pathologist, Byron Collins, once again brings his expertise, this time discussing the likely weapon used to cause the violent trauma to Norma’s head and the nature of the attack. We also introduce retired Homicide Detective Charlie Bezzina to provide some insight into public input into well-publicised crimes.   Murder Archives is written and presented by Emma Curtin. www.muderarchives.com.au Editing and sound by Courtney Carthy Produced in partnership with Nearly   Thanks to all those who added their voices to this podcast (in alphabetical order): Daniel Alfieri Courtney Carthy Simon Curtin Alan Hands Cassidy Krygger Ben Mitchell Elaine Mitchell Gill Neale And our experts: Charlie Bezzina Dr Byron Collins Dr Karen Scally Andrea Scarf
