Dr David Keatley
BSc, MSc, PhD

In addition to being an Associate Professor in Criminology, I have a background in Forensic Psychology. I am also Director of an international research network: Researchers in Behaviour Sequence Analysis (ReBSA) and regularly consult with Law Enforcement Organisations around the world on current and cold cases – specifically in relation to sexual assault, rape, and homicide cases. I am also Director of Forensic Linguistics Analysis Group (FLAG). I am also co-Director of Cold Case Review (CCR) at Murdoch, in which we provide reviews of unsolved cases around the world.

My work and research focuses on complex patterns of (criminal) behaviour in real-world contexts. I typically use Behaviour Sequence Analysis, alongside other methods and techniques to analyse the temporal process of crimes (including interrogation analyses). I am always keen to apply my methods to novel cases, and welcome collaborations from academics and practitioners. I am a full Vidocq Society Member (VSM) and member of the Rhode Island Cold Case Task Force, the PA Homicide Investigators Association (PHIA), and the International Homicide Investigators Association (IHIA), alongside several other national and international cold case initiatives and task forces

For more information about me and my work, please visit my personal website: www.davidkeatley.com, and/or read my books: The Deception Detection Handbook; The Timeline Toolkit; Pathways in Crime

I am the Chair of Crime Science

I am course coordinator for the following:

CRM203 – Criminal Behaviour

CRM301 – Crime Science

CRM306 – Advanced Criminology

MCR602 - Applied Problem Solving Methods in Criminology

I also supervise a number of Research Interns, Hons, MSc, and PhD students

I have been fortunate enough to work with many experts in academia and Law Enforcement  on a range of criminal cases. My research uses a combination of methods (such as Behaviour Sequence Analysis, Crime Script Analysis, Multidimensional scaling, Social Network Analysis, Behaviour Tracking, Winthropping) to understand the temporal processes of different crimes.

My current research interests are:

• (Serial) homicide
• Cold cases
• Timeline reconstruction
• Interrogation analysis (statement analysis and NVC)
• Sexual assault and rape cases
• Burglary

My research focuses on a number of applied criminal areas. The broad outline of current projects are given below:

-Atypical Homicide Profiling (looking for behaivoural patterns in different homicide cases)

-Behaviour Tracking – a new method of tracking movements through spatio-temporal locations

-Crime Linkage – using a newly developed ‘Behaviour Fingerprint’ with the Path Similarity Metric.

-Cold Case Review – using ‘Matrix Sequencing’ to assist with cold case reviews

Please note, owing to the work I do alongside police around the world, I am unable and unwilling to give public talks or expert opinion pieces on current/cold cases.

I have appeared on several shows and print media, however, this is always and only under the authorisation and support of investigating officers.

Please do not contact me regarding ongoing cases.

I am an international consultant to Law Enforcement Organisations working on current and cold cases. I provide behavioural profiling and interrogation analyses.

I have worked on a multiple major crimes cases, both current and cold. Please contact me for more information (but note, I will not give details of any cases I am currently or have previously consulted on)
