Before the introduction of a four-locus multiplex short-tandem-repeat (STR) system into casework, an extensive series of tests were carried out to determine robust procedures for assessing the evidential value of a match between crime and suspect samples.
Twelve databases were analyzed from the three main ethnic groups encountered in casework in the United Kingdom : Caucasians, Afro-Caribbeans, and Asians from the Indian subcontinent.
Independence tests resulted in a number of significant results, and the impact that these might have on forensic casework was investigated.
It is demonstrated that previously published methods provide a simple procedure for correcting allele frequencies - and that this leads to conservative casework estimates of evidential value.
