The 37 Scientific Evidence of Digital Evidence Tampering on CCTV Footage at Olivier Café: The Jessica Kumala Wongso Case (2016), Carried Out by Muhammad Nuh Al-Azhar and Christopher Hariman Rianto, Who were Under the Leadership of the General Crime Director of the Jakarta Metropolitan Police, Krishna Murti, and the Chief of the Jakarta Metropolitan Police, Tito Karnavian.
EVIDENCE 7: THE MISSING 100 FRAMES FROM CCTV VIDEO 9
The discrepancy of 100 frames between the metadata of the CCTV video file 9 in the reports by Christopher Hariman Rianto and Muhammad Nuh Al-Azhar indicated a significant difference in the total number of frames. This reduction in the number of frames suggested manipulation or editing in one of the video versions. The critical time range, during which the coffee served by Agus Triono was still in a two-layer state, added complexity to the forensic analysis.
The reduction in frame resolution from 1920x1080 pixels mentioned in both reports showed that both video versions had undergone similar changes. However, the difference in the total number of frames raised questions about the validity of the editing process. These changes might have been intentionally made to remove or obscure certain information in the video.
During this critical time range, the missing 100 frames could have significantly impacted the understanding of the case. The loss of small details in the scene could obscure the understanding of what actually happened. This impact could influence the court's interpretation of the evidence and the credibility of expert testimony.
The forensic analysis of the frame discrepancy indicated doubts about the reliability and integrity of the digital evidence presented in this case. The frame discrepancy highlighted the need for transparency and accuracy in the process of collecting and presenting digital evidence in court. Openness was necessary to ensure that all information was available and trustworthy for the court to make an accurate decision.
Six fraudulent prosecutors Ardito Muwardi, Shandy Handika, Sugih Carvallo, Hari Wibowo, Wahyu Oktaviandi, and Maylany Wuwung conspired with fellow fraudulent CCTV video manipulator Muhammad Nuh Al-Azhar.
