Can I Challenge DNA Evidence in a Criminal Case?

Can I Challenge DNA Evidence in a Criminal Case?

DNA evidence can be critical in a criminal case. It can help absolve accused persons from criminal defense cases or assist prosecutors in scoring a conviction. However, DNA tests can sometimes be inaccurate. While they can be compelling, a defendant can still challenge DNA evidence in a criminal case and walk free. Here are scenarios where a defendant can challenge DNA evidence in a criminal case.

Weak Readings

A defense attorney can challenge DNA evidence if the readings are weak or inconclusive. Weak readings often occur due to glitches in the testing process, resulting in a low peak height. Low peaks indicate a possible extra contributor to a DNA sample, making the entire process contestable.

Partial Match

A partial match in DNA testing means that the sample has low quantities of the accused’s DNA. It reduces the equation used to calculate the possibility of a match. However, it might indicate that the suspected offender’s relative might be involved. Whatever the case, you can challenge the DNA evidence regardless.

Chain of Custody Issues

You can challenge DNA evidence in a criminal case if you believe the bearers did not preserve or handle the samples appropriately. DNA samples might be susceptible to tampering or contamination. If this is the case, your legal team can challenge the DNA evidence and absolve you from any charges in a criminal case.

Mixed Up DNA Samples

DNA testing can produce more than one contributor at a specific genomic location. If this is the case, your attorneys can challenge the DNA evidence to ensure the testers determine the primary contributor. Sometimes, an officer attending the crime scene might mix up DNA samples if they have to attend multiple scenes, leading to a mix-up.

False Inclusions

DNA testing might include an invalid contributor, making the entire process contestable. You have the right to challenge the DNA evidence for false inclusions through your attorneys.
