How Can DNA Be Used As Evidence For A Crime?
DNA, or
deoxyribonucleic acid, is incredibly powerful when it comes to forensic
science. In some cases, it can serve as near-perfect evidence of a person's
involvement in a criminal act. It can be found in a wide variety of places,
including hair, saliva, semen, and blood. It can be used to support or refute a
suspect's version of events or link the suspect to an unidentified suspect or victim.
On the
technical side, DNA evidence is collected, typically at a crime scene, and then
either tested in a laboratory or compared to databases of other samples. The
comparison of DNA samples can then be used to determine if a suspect is linked
to the crime or not.
Final Verdict:
In
conclusion, DNA evidence is increasingly being used as a reliable form of
evidence in criminal cases. It is used to link suspects to crime scenes and to
refute or support witness testimony, which can significantly help the top
criminal defense lawyer to convince the jury into reaching a more
informed verdict. Although it isn't perfect and may need to be backed up with other
forms of evidence, it can prove to be the deciding factor in certain cases.
