Abstract
‘Investigating crime’ explores how the police investigate criminal activity, setting out the procedures and principles involved and how forensic science provides them with answers. A crime comprises both the criminal act itself and criminal intent. Police investigations have well defined procedures to answer the important questions in a case, such as the Trace, Interview, Eliminate (TIE) method, which collates vast amounts of information to eliminate innocent parties and keep the investigation focused. Forensic evidence is most effective at eliminating people from a TIE inquiry, due to its objectivity and reliability.
