It used to be that if your DNA was found at a crime scene, there was a pretty good chance that not only were you present at that crime scene, but you probably were involved in the crime as well. After all, if your blood was found on the murder weapon or your semen was found on or in the victim, chances are you were probably intimately involved with the person and/or the crime.
In April of 2010, the Scientific Working Group on DNA Analysis Methods (SWGDAM) published a report entitled Interpretation Guidelines for Autosomal STR Typing by DNA Testing Laboratories. This document updates and supersedes the previous SWGDAM Interpretation document released ten years earlier in 2000 and is now being used as guidance in crime labs across the nation.
