Enhancing Criminal Investigations
There have been several changes and variations in the crimes happening in urban and rural areas. The police and the investigation authorities have to explore several options in their process to gather the crime scene evidence, proof and information. On many occasions, the standard practices are seen to have been ineffective, leading to the demand for better and more advanced forensic procedures to be implemented.
DNA Phenotyping
The practice of predicting an organism’s phenotype solely using genetic data obtained via genotyping or DNA sequencing is known as DNA phenotyping. This phrase, also referred to as molecular photo fitting, primarily refers to the estimation of a person’s biogeographic heritage and physical characteristics for forensic purposes.
Forensic Palynology
More lately, forensic palaeontology has been effectively utilised and applied to criminal inquiry. Pollen DNA profiling has yet to be used in forensic investigations, nevertheless. Pollen was once used as a sort of botanical dust debris in several forensic examinations that used dust traces.
Carbon Dating
This scientific process helps to identify the age of the person, food substance or other material that can prove to be useful for answering several questions. It properly deciphers the density and volume of the substance and its deterioration process. The investigating team can comprehend the time passed and the approximate period of crime or incident happening through this unique process.
Forensic Glass Analysis with LA-ICP-MS
The retention of glass after the passive or forced transfer is very high in common apparel made of cotton and wool. Only when there is forced contact between the substance and the glass source will some materials, including metals, soft polymers, and wood, maintain glass transfers.
Touch DNA
This method of forensic identification identifies the DNA from the small traces or deposits of human elements at the location of the crime. Hence this process is called Touch DNA or even Trace DNA. The experts collect samples of everything from the crime scene, including the fingerprints on the objects, the hair strands, the used tissues, the clothes, shoes, fibres of clothing of the suspect, food particles, sweat in wet or dry form, perfume used, dandruff particles, dry skin, etc.
