The investigating officer receives a report from a crime analyst with a number of key elements designed to assist the investigation. It will identify if there are grounds to believe that the offender has previously been identified. It will also provide a breakdown of the behaviour exhibited in the offence, often with a statistical description of some of the elements involved. This can alert an investigator to the importance of some aspects of the offence not immediately apparent. SCAS are also responsible for identifying good practice, or "what works", so the analyst's report may contain "investigative suggestions" that might guide the officer to a specific line of enquiry not yet considered. The report may also suggest possible suspects that the unit has identified from a number of databases. When a prime suspect has been identified and charged with an offence, senior analysts are able to provide specialist evidence in court, to assist with the prosecution of offenders.
