Assessment of changes to DNA database interrogation at Forensic Science SA

Research output: Contribution to journalArticlepeer-review


The ultimate goal of database casework is to supply investigative information to authority agencies. Traditionally this has been accomplished by direct matching. Recently, Forensic Science SA (FSSA) made changes to the DNA profile upload criteria for direct matching. This was made possible in-house by the introduction of a new Laboratory Information Management System (LIMS). In conjunction with direct matching for database investigations, FSSA also routinely perform mixture searches on unresolved DNA mixtures using the expert forensic software STRmix. Data from the FSSA no suspect workflow was collected for a 10 month period from September 2017 to June 2018 to determine the impact of these two changes compared with previous direct matching processes over the same period. The data demonstrate an increase in investigative information provided to the South Australian Police (SAPOL) by FSSA.
