Legal DNA Testing: Understanding the Role of DNA Tests in Criminal Investigations and Forensic Science

How does legal DNA testing work? Deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions for building and maintaining an organism. DNA is found in every cell of the body, and it is unique to each individual. This makes DNA a powerful tool for law enforcement, as it can be used to identify suspects and link them to crimes.

How Does DNA Testing Work?

DNA testing works by comparing the DNA of a suspect to the DNA found at a crime scene. If the DNA matches, it provides strong evidence that the suspect was at the scene of the crime. DNA testing can also be used to exclude suspects from a crime, as no two people have the same DNA.

What Types of DNA Tests Are Used in Criminal Investigations?

There are a variety of DNA tests that can be used in criminal investigations. Some of the most common types of tests include:

* STR testing: STR stands for short tandem repeats. STRs are short sequences of DNA that are repeated multiple times in a row. STR testing is a very accurate way to identify individuals, and it is the most common type of DNA test used in criminal investigations.

*Y-STR testing: Y-STR testing is a type of DNA testing that looks at the DNA found on the Y chromosome. The Y chromosome is passed down from father to son, so Y-STR testing can be used to identify male suspects.

* mtDNA testing: mtDNA stands for mitochondrial DNA. Mitochondrial DNA is passed down from mother to child, so mtDNA testing can be used to identify female suspects.

* CODIS testing: CODIS stands for Combined DNA Index System. CODIS is a database of DNA profiles from convicted offenders and crime scene evidence. CODIS is used to link crimes and identify suspects.

How Effective Is DNA Testing in Criminal Investigations?

DNA testing is very effective in criminal investigations. In fact, DNA evidence has been used to solve thousands of crimes, including murders, rapes, and assaults. DNA evidence is also being used to exonerate people who have been wrongfully convicted of crimes.

Is DNA Testing Legal?

The use of DNA testing in criminal investigations is legal in the United States. However, there are some restrictions on how DNA testing can be used. For example, DNA testing cannot be used to discriminate against people based on their race or ethnicity.

What Is Forensic DNA Testing?

What is forensic DNA testing? DNA testing is essential for the research process. Various fields rely on DNA testing (for instance, forensic science, genealogy, agriculture, medicine, and many more). DNA stands for the term deoxyribonucleic acid. DNA helps human cells function properly. In fact, DNA is the blueprint that contains information for encoding proteins and other components of the cell. You can understand how essential DNA testing is through medical, research, and judicial perspectives. Below, we will talk about how important DNA is for Forensic testing and how professionals perform Forensic DNA testing.

Forensic DNA Testing

DNA Testing for Forensic Science

Results from DNA testing can identify every individual separately. Authorities can apprehend a lot of criminals and solve cases with the help of Forensic DNA testing. In forensic DNA testing, investigators collect tissue samples from hair or blood found on the crime scene. After that, the technician identifies the person present at the crime scene or possibly involved in the crime. Results from forensic DNA testing also hold up as evidence in court. To reach a verdict, the police and judiciary system depends on DNA fingerprinting results’ power and credibility.

Sources of DNA Evidence

Scientists can determine the DNA profile through various body parts. These include cells, tissue, bone, teeth, hair, feces, urine, saliva, semen, and blood.

Through advancing technology, forensic scientists are developing the ability to analyze even smaller biological samples to develop a DNA profile. For instance, if someone touched a weapon or an object, they might leave some skin cells behind. Professionals refer to this type of DNA as touched DNA. They can also collect this DNA from bruises or the skin of victims, both alive or deceased.

When fingerprints are hard to retrieve, low-level DNA samples can be helpful. They can find these samples from gun handles, dashboards of the vehicle, or any other surface. However, only limited jurisdiction can process these types of evidence.

Technicians will compare the suspect’s DNA profile or the victim to the DNA recovered from the crime scene. For that, the laboratory should have their known samples ready so that they can compare them easily. Analysts call these samples reference samples. Various jurisdictions collect samples from the arrestee daily during fingerprinting and booking. However, this law about collecting samples from the arrestees is evolving and can vary depending on states. TO collect the reference from an arrestee, they sometimes require an order from the court. Investigators can gather Reference samples from the suspect unless they are not cooperating. For that, they will need a court order.

Other than reference samples, investigators will also collect elimination samples from other personnel. These can include first responders, analysts, and crime scene personnel who are working on the case. By testing their samples, investigators can eliminate them from the investigation.

Properly collecting the biological evidence is essential, but preserving it is more so. Exposure to humidity or heat may degrade the samples. Therefore, technicians store evidence in a cool environment. If the stains are dry, storing them in a cool place rather than at room temperature is unnecessary. However, the samples should be away from any humidity. Liquid samples should be in an insulated or refrigerated container.

Who Conducts DNA Analysis

DNA analysts who are working in the laboratory participate in the NDIS (National DNA Index System). Analysts should receive their certification from a recognized organization such as AABB and the specific training and educational requirements. The minimum requirement is a bachelor’s degree in chemistry, biology, or in a field related to forensic science. Furthermore, the analyst must complete nine hours at a graduate or undergraduate level in various subjects. These include molecular biology, genetics, biochemistry, etc. They should also have training or course work in population genetics or statistics as they are essential to forensic DNA analysis.

For ensuring the analysts’ skills are up to date, the analysts working in a criminal laboratory should also update their education. The FBI has defined these requirements in the QAS or Quality Assurance Standards. You can refer the specialist conducting the DNA analysis in a laboratory with various titles, such as Forensic Laboratory Analyst, Forensic Scientist, Forensic Examiner, and Crime Laboratory Analyst.

How Forensic DNA Testing is Done

The DNA samples that a laboratory receive go through the following steps:

1.    Extraction

The analyst will release the DNA from the cell.

2.    Quantitation

Next, they will define the quantity of DNA.

3.    Amplification

For characterizing the DNA, the analyst will produce multiple copies.

4.    Separation

This process permits the identification of the amplified DNA through separation.

5.    Analysis and Interpretation

This is the qualitative and quantitative comparison of the DNA evidence from the DNA profiles.

6.    Quality Assurance

In this process, the analyst’s reports undergo reviews for technical accuracy.
