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 11:
CCTV 7 FOOTAGE FROM 17:17 TO 18:39 LOCAL TIME WAS REDUCED IN FRAME DIMENSIONS TO 960 x 576 PIXELS
The deliberate downscaling of CCTV 7 footage from 1920x1080 pixels to 960x576 pixels and the reduction of the frame rate from 25 frames per second to 10 frames per second, executed by forensic experts Muhammad Nuh Al-Azhar and Christopher Hariman Rianto, had profound forensic implications. This manipulation severely compromised the quality of the footage during a critical time frame, from 17:17 to 18:39 local time, which encompassed key moments necessary for a thorough forensic analysis of the events leading to Mirna Salihin’s death on January 6, 2016.

At 17:19:30 local time, Mirna Salihin was purportedly seen not taking a straw from the table and instead directly sliding the glass and drinking from the straw already in the glass. The original high-resolution footage would have allowed a detailed observation of her hand movements and the position of the straw, which was crucial to establish whether Jessica Wongso had placed the straw in the glass earlier, as alleged. The reduced resolution obscured these subtle but critical details, making it challenging for forensic analysts to accurately determine the sequence of actions.

Furthermore, at 17:19:34 local time, the video showed Hani Juwita Boon bringing the coffee cup close to her mouth and only smelling it. However, her testimony as a witness indicated that she had consumed a small amount of coffee. This discrepancy could have been better analyzed with high-resolution footage, which would have provided clearer visual evidence of her actions. The downscaled video compromised the ability to distinguish whether she merely smelled the coffee or actually sipped it, which is vital for understanding the sequence of events and assessing the credibility of her testimony.
Dr. Adiyanto from Abdi Waluyo Hospital testified that Hani Juwita Boon admitted to him that she drank the coffee and feared dying like Mirna Salihin. This statement is crucial, as it directly contradicts the visual evidence provided by the manipulated footage. The reduced frame rate made it difficult to observe the precise moment and manner in which Hani interacted with the coffee cup, creating a gap in the forensic narrative that should have been clear and unambiguous.

After drinking the coffee, Mirna Salihin reportedly waved her hand in front of her mouth multiple times, an action that was captured at a reduced frame rate of 10 fps. The original 25 fps would have provided smoother and more continuous visual data, allowing for an accurate analysis of her ph

00:00Australian resident Jessica Wongso has been charged with the murder of Minis Alihin.
00:11Police allege she poisoned her friend by adding cyanide to her coffee.
00:15Deep inside is something like the evil, you know.
00:25The trial of the century.
00:29Since 11, CCTV7 footage from 1717 to 1839 local time was reduced in frame dimensions
00:36to 960x576 pixels.
00:40The deliberate downscaling of CCTV7 footage from 1920x1080 pixels to 960x576 pixels, and
00:48the reduction of the frame rate from 25 frames per second to 10 frames per second, executed
00:54by forensic experts Mohamed Nuh Al-Azza and Christopher Harriman-Rianto, had profound
00:59forensic implications.
01:00This manipulation severely compromised the quality of the footage during a critical time
01:05frame, from 1717 to 1839 local time, which encompassed key moments necessary for a thorough
01:11forensic analysis of the events leading to Myrna Salihin's death on January 6, 2016.
01:19At 17 hours 19 minutes and 30 seconds local time, Myrna Salihin was purportedly seen not
01:24taking a straw from the table and instead directly sliding the glass and drinking from
01:29the straw already in the glass.
01:31The original high-resolution footage would have allowed a detailed observation of her
01:35hand movements and the position of the straw, which was crucial to establish whether Jessica
01:39Wongso had placed the straw in the glass earlier, as alleged.
01:44The reduced resolution obscured these subtle but critical details, making it challenging
01:49for forensic analysts to accurately determine the sequence of actions.
01:53Furthermore, at 17 hours 19 minutes and 34 seconds local time, the video showed Hani
01:59Jawida Boon bringing the coffee cup close to her mouth and only smelling it.
02:04However, her testimony as a witness indicated that she had consumed a small amount of coffee.
02:10This discrepancy could have been better analyzed with high-resolution footage, which would
02:15have provided clearer visual evidence of her actions.
02:18The downscaled video compromised the ability to distinguish whether she merely smelled
02:23the coffee or actually sipped it, which is vital for understanding the sequence of events
02:27and assessing the credibility of her testimony.
02:30Dr. Adianto from Abdiwaluyo Hospital testified that Hani Jawida Boon admitted to him that
02:35she drank the coffee and feared dying like Myrna Salihin.
02:39This statement is crucial, as it directly contradicts the visual evidence provided
02:43by the manipulated footage.
02:46The reduced frame rate made it difficult to observe the precise moment and manner in which
02:50Hani interacted with the coffee cup, creating a gap in the forensic narrative that should
02:54have been clear and unambiguous.
02:57After drinking the coffee, Myrna Salihin reportedly waved her hand in front of her mouth multiple
03:02times, an action that was captured at a reduced frame rate of 10 frames per second.
03:07The original 25 frames per second would have provided smoother and more continuous visual
03:12data, allowing for an accurate analysis of her physical reactions.
03:17The reduced frame rate resulted in choppy footage, making it challenging to discern
03:21the nuances of her gestures and physiological responses, which are critical in determining
03:26her condition and the onset of symptoms.
03:30The forensic impact of downscaling the CCTV7 footage was significant, especially concerning
03:35the ability to accurately analyze key visual details.
03:40The reduced resolution made it impossible to precisely determine the volume of coffee
03:44before and after Myrna Salihin consumed it, as well as before and after Hani Jawida Boone
03:49allegedly sipped it.
03:51High-resolution footage would have allowed forensic experts to use edge detection, motion
03:56detection, and other advanced forensic techniques to measure the remaining volume of coffee
04:01in the glass at various critical points.
04:03This information could have verified the claims of how much coffee was actually consumed
04:08by Myrna and Hani, providing crucial evidence about the sequence of events.
04:12Additionally, the downscaled footage hindered the analysis of the coffee's color at table
04:1754 when Myrna Salihin drank it.
04:21The original footage could have shown whether the coffee had a darker color, indicating
04:25the presence of cyanide, as alleged by toxicologists Nursimran Subandi and Aimade Agus Gel-Gel.
04:31This analysis was crucial because a darker color in the coffee could support the hypothesis
04:36that the beverage contained cyanide, which would significantly impact the forensic and
04:40toxicological assessment of the case.
04:43The downscaling destroyed the resolution necessary to make these comparisons, thus obscuring
04:48potentially vital evidence that could have confirmed or refuted the presence of cyanide
04:53in the coffee.
04:54This manipulation directly undermined the ability to conduct a thorough and accurate
04:58toxicological analysis, impeding the reconstruction of events and the establishment of a clear
05:04forensic narrative.
05:06The motive behind manipulating this digital evidence appears to be to obscure critical
05:10details that could exonerate Jessica Wongso, or at least provide a clearer understanding
05:15of the events.
05:17By degrading the quality of the footage, Mohamedna Al-Azza and Christopher Harriman Rianto made
05:22it difficult for forensic analysts to draw definitive conclusions from the visual evidence.
05:27This manipulation not only compromised the integrity of the forensic analysis, but also
05:32potentially influenced the judicial process by presenting a distorted version of the events,
05:37thus impeding the pursuit of justice.
