Yes, DNA evidence can be used in court to establish a person’s identity or link them to a crime scene. It is considered highly reliable and persuasive evidence.

DNA can be collected through various methods, such as swabbing the inside of a person’s cheek or collecting samples from blood, hair, or other bodily fluids. Law enforcement agencies follow specific protocols to ensure the integrity of the collected DNA.

Yes, DNA testing can potentially prove someone’s innocence by excluding them as the source of the DNA found at a crime scene. This has led to the exoneration of numerous individuals who were wrongfully convicted.

Yes, DNA testing is commonly used to determine paternity. It compares the DNA profiles of the alleged father, child, and mother (if available) to establish biological relationships with a high degree of accuracy.

Yes, DNA evidence can be used in civil cases, such as child custody disputes or inheritance claims, to establish biological relationships or prove or disprove allegations of paternity.

In certain circumstances, DNA evidence can be collected and used against an individual without their consent. For example, if a person is arrested for a crime, their DNA may be collected as part of routine booking procedures.

Refusing to provide a DNA sample when requested by law enforcement can have legal consequences, as it may be considered obstruction of justice or non-compliance with a lawful order. However, the specific laws regarding DNA sample collection vary by jurisdiction.

The storage duration of DNA evidence varies depending on the jurisdiction and the nature of the case. In some cases, DNA evidence may be stored indefinitely, especially in serious criminal cases or unsolved cases.

While DNA evidence is generally considered reliable, there is a possibility of contamination or tampering. Proper collection, handling, and storage procedures are followed to minimize these risks, and defence attorneys often have the opportunity to challenge the integrity of DNA evidence in court.

The ability to request the destruction of a DNA sample after a case is closed depends on the jurisdiction and the specific circumstances. In some cases, DNA samples may be retained for future reference or for potential retesting if new technologies become available.
