The possibility of confirming an individual’s identity by DNA matching makes the collection of cellular material left at the crime scene mandatory. Each scene presents its own difficulties and unless the investigator is prepared to collect any and all potential sources of DNA, valuable evidence may be lost. The most frequent forms of forensic evidence available for DNA testing found at the crime scene are: fresh blood, semen, hair roots and clothing stained by physiological fluids.
