Good Get, Bob
Melville it was. The full story is a bit more interesting than the account in the source you have quoted. In one of my sources it is reported that Mrs Melville displayed the body, all decked out with ribbons and flowers, in her Melbourne Oyster Shop. It sure would not have encouraged me to buy some oysters there!
"Melvilles wife and friends applied to have his body released to them and their wish was granted. They took his body, decorated it with flowers and ribbons an displayed it in the window of an oyster shop in Little Bourke Street. Whether they did it because they were upset about his death or as the popular newspapers reported, because they used it to increase custom at the oyster shop, we will never know. After the Melville incident all convicted criminals bodies were buried in unmarked graves within the prison grounds"
Over to you...
