Until the late 19th century, the success of criminal investigations largely hung on witness reports and (often extorted) confessions. A lack of scientific tools meant investigators needed advanced deductive reasoning abilities – and even then they’d often hit a dead end.
Today, investigations demand an interdisciplinary and high-tech approach, involving experts from diverse scientific disciplines. Stabbing investigations are particularly important, as fatal stabbings are the leading cause of homicide in countries with restricted access to firearms, including Australia.
