Recently there has been an increasing interest in improved DNA testing techniques and the interpretation of these.  For example, LCN and Real-Time PCR are two instances of improvements in technology that have advanced the applications of DNA testing in forensic science.  More recently the use of familial searches has also generated attention with the "Grim Sleeper" case in Los Angeles.
 
This virtual issue of papers published over the last few years in the Journal of Forensic Sciences includes information on the analysis of DNA in degraded and unusual specimens.  These have application in criminalities, physical anthropology, deontology and the identification of victims of mass disasters. They demonstrate how DNA testing has become common place in the forensic sciences. - Michael Peat, Editor
