DNA analysis is the powerful cue in Criminal investigation blended with AI grouped technologies

 In the rapidly transforming digital era, criminal investigation has been remodeled for identification of accused and forensic application to accelerate the process of legal proceedings. Recently with a heap of crime cases, criminal investigation has become a major challenge for forensic experts, investigators and criminal lawyers. When crime is committed, police officers rush to crime locations to instantly comprehend the nature of crime, take critical decisions on the basis of sensitive data and evidences available at the crime scene. After preliminary examination, the critical role of a criminal expert is to retain the evidence, people involved in crime and to formulate a decisive plan for further investigation.

Several criminal investigation techniques are adopted by forensic experts to detect the criminals. DNA analysis as a criminal investigation technique emerges as a foolproof and quickly recognizes the accused on the crime scene. DNA analysis is a biological process to identify and examine genetic material present in an individual’s cells. AI has extended its technological innovation in DNA matching to pinpoint guilty in dangerous crime happenings. AI powered tools have expedited the accuracy of data collection and storing to maintain the DNA evidence.

In the DNA analysis technique of crime investigation, a biological DNA sample from crime acts is carefully taken and preserved properly so that it can be compared with the sample of known offenders in a police database. For DNA samples, experts collect evidence from blood, semen, skin cells, tissue, muscle, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine etc. This will help forensic experts to isolate people who are not involved in crime in order to give them justice. DNA analysis will be beneficial to identify hardcore criminals. DNA evidence is a key marker in crime investigations to detect the guilty and to vindicate innocents. Crime investigative staff such as victim service providers, crime scene technicians, nurse examiners, and other medical workers must be adroit in crime data collection, transporting, and storage of DNA samples. Medical personnel must preserve the DNA evidence safely so that it should not mix with the DNA from another source to maintain morality in justice. Other external factors such as heat and humidity may also contaminate DNA evidence and may lead to misleading outcomes. DNA evidence can get destroyed in poor plastic packaging as bacteria can grow and degrade the collected biological evidence. AI algorithms precisely compare DNA samples and identify the suspect in cracking cold cases too. AI led technologies such as deep learning, or machine learning can do miracles in predicting physical traits of guilty or accused such as hair color, eye color, and facial features referring to DNA evidence. AI can assist in drawing sketches of suspects through analyzing DNA samples. Technology innovation can have a promising impact on criminal investigation and aid law enforcement to provide justice.   

Overall DNA analysis technique of criminal investigation guarantees in detecting offenders and fair justice to the victim whether they are live or not. DNA analysis technique is immensely effective to examine violent nature of crimes such as murders or rape cases, hyper domestic violence and armed robbery because crime experts can collect blood, semen or saliva of the committer or victim for DNA profiling.

DNA outlining is a progression in the legal arena and equips law enforcement professionals to crack very old crime cases on the basis of DNA material such as fingernail clippings. Application of machine learning in DNA analysis is the major breakthrough in the criminal justice system to blow a principled message to the whole civilization.

Final word:

Legal process is gaining new heights to offer justice to victims. To quicken the investigative process, DNA testing combined with AI algorithms is a distinct and proven technique for detecting crooks. DNA analysis provides a precise outcome to recognize suspects because every person has different DNA makeup except identical twins. AI offers modern computational procedures to analyze and interpret genetic data. Medical staff responsible for collecting DNA samples from crime scenes must be knowledgeable and carefully pick biological evidence such as saliva, blood strains to prevent contamination. DNA evidence can be obtained from crime spots to locate accused or identify defendants among many suspicious people.
