Pretoria - A senior police forensic analyst has detailed to the High Court in Pretoria the techniques used in analysing close-circuit television (CCTV) footage to map out the movements of four men accused of the murder of North West businessman, Wandile Bozwana and his business partner and lover Mpho Baloyi.
Captain Ludumo Gqotso, who took the witness stand on Wednesday for the prosecution, told the court that on 23 November 2015 he received a sealed exhibit bag with four storage devices, two USBs and two DVD discs, each sealed in a separate exhibit bag, from the investigating officer.
He then set out to analyse the footage in the storage devices by capturing images and using image enhancement techniques to enlarge and brighten the images for a clearer view.
“My role was to capture images, enhance those that were not clear and compile a picture album,” he said.
Gqotso, who has more than 12 years experience as a forensic analyst, said he then used arrows on the images to mark the suspects as well as Bozwana and Baloyi.
