DNA Evidence (Forensic)
Genetic material analysis used to identify or exclude a person as being connected to a crime scene or offence, based on biological samples.
DNA evidence has become an important tool in criminal investigation, particularly in cases of sexual assault, and courts generally treat a properly conducted DNA match, together with a maintained and unbroken chain of custody of the sample, as strong corroborative evidence.
Challenges to DNA evidence commonly focus on whether the sample collection, storage, and testing process was free of contamination or procedural lapses.
