Collecting samples for DNA analysis at crime scenes is a critical part of investigating the nature of the crime. The proper collection and preservation of evidence can establish a connection between the scene and a suspect. Precise collection records and established methods are required for crime scene sample analysis. Preservation of the biological evidence is crucial since crime investigations can take place over long periods of time. Analyzing and comparing crime scene and reference samples can take between months and years to complete. It is important, therefore, to collect the samples on a medium that can stabilize the genetic material.
