Dubai Police reveal those involved in a murder with advanced technology

Muhammad Khaled Al Rahma: “The role of DNA profiling comes if it is impossible to obtain a decimal fingerprint from crime scenes.”

The Director of the International Center for Forensic Sciences in the General Department of Forensic Evidence and Criminology in Dubai Police, Chairman of the Council of Scholars, Lt. Colonel Dr. Rashid Al Ghafri, revealed the use of a precise scientific specialty known as DNA profiling, in revealing complex cases, explaining that it is one of the precise scientific disciplines that It requires experts to review its scientific and technical developments, in order to reach verified results that serve the work of investigators at crime scenes.

Al-Ghafri said that the administration was able, by using DNA profiling, to prove the existence of genetic fingerprints for a number of suspects in a murder that took place last year, pointing out that they left their fingerprints by touch, but they contained only a limited percentage of DNA, so an advanced technology was used to thicken the DNA, which Contributed to finding the perpetrators and proving their presence at the crime scene.

For his part, an assistant expert in the Department of Biology and DNA in the General Department of Forensic Evidence and Criminology, First Lieutenant Muhammad Khaled Al Rahma, stated that the role of DNA profiling comes if it is impossible to obtain a decimal fingerprint from crime scenes to examine and infer its owner, so we search for genetic fingerprints such as Blood, fluids, hair and fingerprints left on touch surfaces.

Al Rahma, who holds a master’s degree in DNA profiling from the University of Central Lancashire in the United Kingdom, added with distinction, “The fingerprints left by touch are sometimes weak and insufficient to reach the identity of their owner, so we use a sophisticated mechanism to raise samples called (Touch). DNA), so the expert raises the genetic fingerprint of a small amount from the crime scene according to several approved methods in the laboratory, and intensifies the sample to obtain a larger quantity that enables the identification of its owner, and this can only be done by samples that were left by touch at crime scenes.”

He pointed out that he had been able to provide 339 positive samples since the beginning of this year, and his research included reducing the percentage of unknown cases by identifying the DNA.

He added that he made reference comparisons with the best international practices of how to raise biological samples, and their impact on the materials used to detect the decimal fingerprint, and the possibility of using new swabs to raise biological samples, and their impact on the issues received by the Department.
