The considerable identifying power of DNA can see it treated as an absolute form of evidence, rather than as any other trace evidence. This study aimed to provide data into the abundance, transfer and persistence of trace DNA, in a particular crime scenario-residential burglary. Background levels of DNA on common burglary entry points were found to be low, however transfer of DNA during the action of a break-in is also low. The ability to recover analyzable DNA from outdoor surfaces decreases rapidly over several weeks. © 2008 Elsevier Ireland Ltd. All rights reserved.
