Abstract

Touch DNA profiling is an important tool to solve the mystery of many cases, especially when other biological evidences cannot be found in crime scene. However, there are many variables that influence Touch DNA profiling such as recovery techniques and extraction. In addition, effect of environmental factors on items found outdoor such as sand can impact on the process. Therefore the aim of this experiment was to test how sandy surfaces can affect the recovery of Touch DNA Profiling by validation two recovery methods and two extraction kits that are widely used in the DNA forensic field.
