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 6: THE LOSS OF 50 FRAMES FROM TAMPERED CCTV 7 FOOTAGE
A forensic analysis of the 50-frame discrepancy in CCTV video 7 indicated a significant impact on the integrity of the digital evidence. This frame discrepancy raised suspicions that one or both versions of the video had been manipulated or edited. During the critical timeframe when Jessica was suspected of aligning a paper bag and inserting cyanide, the presence or absence of these 50 frames could have affected the clarity of the event.
The reduction in video frames by removing 50 frames could have caused the loss of crucial details necessary to accurately understand the sequence of events. For instance, if the scenes between 16:28:40 WIB and 16:29:50 WIB were among the missing 50 frames, it could obscure vital information such as Jessica's hand movements or objects that might have been present in those scenes. Such a significant loss of visual information could cast doubt on the reliability of the evidence presented in court.
Furthermore, the discrepancy in the number of frames between the reports of Christopher Hariman Rianto and Muhammad Nuh Al-Azhar highlighted inconsistencies and a loss of integrity in the evidence presented by both forensic experts. The 50-frame discrepancy raised questions about the reliability of the digital evidence collection and presentation process in this case. This inconsistency could lead to uncertainty and doubt about the experts' testimonies and potentially influence the final decision in the trial.
The forensic impact was that the absence of the 50 frames in the downscaled video version could obscure the complete picture of events that occurred during the critical timeframe. This not only affected the court's ability to make an informed decision based on the available evidence but also cast doubt on the validity of the forensic experts' testimonies and analyses. This situation underscored the importance of maintaining the integrity of digital evidence in the judicial process to ensure that true justice is achieved.
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.

00:00Australian resident Jessica Wongso has been charged with the murder of Minis Alihin.
00:09Police allege she poisoned her friend by adding cyanide to her coffee.
00:13Jessica is like a demon.
00:16Deep inside is something like evil.
00:19It is said that the trial of the century is true.
00:28Evidence 6, the loss of 50 frames from tampered CCTV7 footage.
00:33A forensic analysis of the 50 frame discrepancy in CCTV video 7 indicated a significant impact
00:40on the integrity of the digital evidence.
00:43This frame discrepancy raised suspicions that one or both versions of the video had been
00:47manipulated or edited.
00:49During the critical time frame when Jessica was suspected of aligning a paper bag and
00:54inserting cyanide, the presence or absence of these 50 frames could have affected the
00:58clarity of the event.
01:00The reduction in video frames by removing 50 frames could have caused the loss of crucial
01:05details necessary to accurately understand the sequence of events.
01:09For instance, if the scenes between 1628 and 40 seconds Western Indonesian time and 1629
01:16and 50 seconds Western Indonesian time were among the missing 50 frames, it could obscure
01:21vital information such as Jessica's hand movements or objects that might have been
01:25present in those scenes.
01:28Such a significant loss of visual information could cast doubt on the reliability of the
01:32evidence presented in court.
01:34Furthermore, the discrepancy in the number of frames between the reports of Christopher
01:38Harriman-Rianto and Mohamed Nah Al-Azza highlighted inconsistencies and a loss of integrity in
01:43the evidence presented by both forensic experts.
01:47The 50-frame discrepancy raised questions about the reliability of the digital evidence
01:51collection and presentation process in this case.
01:55This inconsistency could lead to uncertainty and doubt about the experts' testimonies and
02:00potentially influence the final decision in the trial.
02:04The forensic impact was that the absence of the 50 frames in the downscaled video version
02:08could obscure the complete picture of events that occurred during the critical time frame.
02:13This not only affected the court's ability to make an informed decision based on the
02:17available evidence, but also cast doubt on the validity of the forensic experts' testimonies
02:22and analyses.
02:24This situation underscored the importance of maintaining the integrity of digital evidence
02:28in the judicial process to ensure that true justice is achieved.
02:32Furthermore, the forensic impact of the downscaled video clip with 50 missing frames, where Jessica
02:37Wongso was accused of moving the stirrer from the table into Myrna Salihan's glass, aligning
02:42a paper bag, and inserting cyanide into Myrna Salihan's coffee cup, is significant.
02:48First, the missing frames could result in a loss of crucial details that are essential
02:53for accurately understanding the sequence of events.
02:57If the missing frames contained key actions, such as Jessica's hand movements or the placement
03:02of objects, their absence could obscure critical evidence.
03:06This could potentially lead to misinterpretations or doubts about what actually occurred during
03:10the critical time frame.
03:12Second, the integrity of the digital evidence is compromised by the reduction in resolution
03:17and the missing frames.
03:19Any gaps or sudden jumps in the video could suggest tampering or editing, raising questions
03:24about the authenticity of the footage.
03:27This inconsistency could undermine the reliability of the evidence presented in court and cast
03:31doubt on the overall case against Jessica.
03:34Additionally, the discrepancy in the number of frames could create uncertainty and confusion.
03:41It could lead to different interpretations by forensic experts, which in turn could affect
03:45their testimonies and analyses.
03:47This inconsistency may introduce reasonable doubt, impacting the court's ability to make
03:52a well-informed decision based on the available evidence.
03:56Overall, the forensic impact of the downscaled video with missing frames is substantial.
04:02It affects the clarity and reliability of the evidence, potentially influencing the
04:06outcome of the trial and the justice delivered.
