Abstract	Physical evidence has historically formed the cornerstone of criminal prosecution; however, research indicates that it is collected in fewer than 10 per cent of cases investigated by police, suggesting that the absence of recoverable physical evidence is far more common than the exception. This paper examines the psychology of the trace-less crime from two complementary angles. First, it analyses the psychological and cognitive processes underlying deliberate forensic avoidance, including forensic awareness, the motivational architecture of detection avoidance, the role of media exposure in informing offenders' countermeasures, and the typological distinction between organised and disorganised offenders in relation to evidence elimination. Second, it examines what behavioural clues remain even when physical evidence has been deliberately eliminated or was never present, with particular attention to modus operandi, psychological signature, crime scene staging indicators, and the role of victimology and spatial behaviour as behavioural evidence. The paper draws on forensic psychological research, crime scene analysis literature, and investigative psychology to argue that the attempt to achieve a trace-less crime is itself a form of behaviour that generates its own distinctive evidence record, one that, while different in kind from physical forensic evidence, is interpretable through the frameworks of behavioural analysis and can serve as the primary basis for investigative inference when no physical evidence exists.
