New foren­sic de­vices to help po­lice scan crime scene data in­stantly

dubai — A first-of-its-kind ‘foren­scope’ that can in­stantly process fin­ger­prints, DNA sam­ples and doc­u­ments found at the crime scenes and a 3D face scan­ner are some of the top in­no­va­tions be­ing show­cased by the Dubai Po­lice at the Emi­rates Foren­sic Con­fer­ence and Ex­hi­bi­tion.

The three-day event, ex­plor­ing ‘how sci­ence can serve jus­tice’, kicked off at the Dubai In­ter­na­tional Con­ven­tion and Ex­hi­bi­tion Cen­tre on Mon­day.

Lieu­tenant Ab­dul Rah­man Al­haj, ex­pert as­sis­tant at the fin­ger­print sec­tion of the Dubai Po­lice Foren­sic Depart­ment, said that po­lice of­fi­cers have to cur­rently col­lect sam­ples from the crime scene and then phys­i­cally trans­port them to the po­lice depart­ment for further in­ves­ti­ga­tion. How­ever, once the Dubai Po­lice adopt the new foren­scope, a lot of time can be saved as the de­tails of the fin­ger­prints, DNA sam­ples and doc­u­ments can be elec­tron­i­cally pro­cessed at the crime scene and trans­ferred to the depart­ment within sec­onds.

He added: “The de­vice is ba­si­cally an an­droid tablet with a cam­era, which can be used to cre­ate and save ev­ery case sep­a­rately. It has six types of lights with UV and IR wave­lengths.

“For tak­ing fin­ger­prints, we use UV light. It has two lenses — one for read­ing the DNA and doc­u­ments and the other lens for read­ing fin­ger­prints. Af­ter cap­tur­ing im­ages, we have the op­tion to edit, take mea­sure­ment, crop, add text, and so on.”

He also demon­strated how the de­vice can use its in­frared light to read the orig­i­nal text an ink soaked or splat­tered doc­u­ment.

One of the other unique de­vices on dis­play was the 3D face scan­ner that was im­ple­mented by the Dubai Po­lice about nine months ago. It is used to com­pare sus­pects with footage or ev­i­dence from CCTV, to aid iden­ti­fi­ca­tion.

Ma­jor Dr Ha­mad Alawar, head of the video and im­age foren­sic sec­tion at the Dubai Po­lice, said: “It helps us in­crease the ac­cu­racy of our foren­sic re­ports when it comes to com­par­ing sus­pects with any piece of ev­i­dence — videos, CCTV or im­ages, and it al­lows us to eas­ily in­ves­ti­gate it in a lot of de­tails. It in­creases our speed and ac­cu­racy.”

He demon­strated how the scan­ner works, on his col­league. “Using my col­league as an ex­am­ple here, you get to cap­ture his face in 3D. You don’t need to call the sus­pect again to take any more photographs. You can do any kind of com­par­isons of it from any an­gle, zoom­ing in to find any marks. You can com­pare the fa­cial fea­tures with more pre­ci­sion.”

As of now, the Dubai Po­lice foren­sic lab only has one such de­vice for 3D iden­ti­fi­ca­tion.

Be­sides many such in­no­va­tive de­vices, the foren­sic event fea­tures seven work­shops, 20 ex­hibitors and more than 30 sci­en­tific lec­tures and 70 sum­maries.

The Dubai Po­lice’s new ad­vanced de­vices, for 3D face scan­ning and fin­ger­print pro­cess­ing, which can save cru­cial in­for­ma­tion.
