ABSTRACT

Not finding a murder victim poses challenges for homicide investigators in solving crime, including determining where to search for the deceased’s body. Existing literature focuses on locating offenders through criminal profiling; however, this is largely based on identification through forensic evidence found at the murder site or where the victim was located. This paper considered the challenge of locating a deceased victim from the perspective of search coordinators assisting homicide investigations. Could reference to previous homicide cases provide patterns and trends that may assist in locating disposed victims quicker, thus aiding in preserving vital physical evidence and providing expedient closure for the community?

METHODS: Through generation of a dataset utilising all Queensland Police recorded homicides from 2004 to 2020 inclusive, statistical analysis was conducted using SPSS™ software to identify common trends and characteristics of victim disposal. These identified commonalities were used to develop the Disposed Homicide Victim Matrix (DHVM), and Search Coordinator Principles, as tools to assist search coordinators in future relevant cases.

RESULTS: The study identified four (4) key commonalities observed in the dataset, (1) East is the predominant direction for victim disposal; (2) The offender’s vehicle was the most common method of victim transport followed by carrying/dragging; (3) concealment with leaf litter and local debris was the norm, followed by no attempt at concealment; and (4) victims were moved less than 50 m from a road or track after transport.

CONCLUSION: The DHVM can assist police search for these victims by narrowing down potential search locations. Finding a victim has implications throughout the community, providing evidence that could secure a conviction, allowing a measure of grief closure to the co-victims, and inspiring confidence in police.
