EVIDENCE 9: MUHAMMAD NUH AL-AZHAR DELIBERATELY DOWNSCALED CCTV 2 FOOTAGE
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 9:
CCTV VIDEO 2 FROM 13:55 TO 16:02 LOCAL TIME WAS REDUCED IN FRAME DIMENSIONS TO 960x576 PIXELS
Muhammad Nuh Al-Azhar deliberately performed downscaling on CCTV 2 footage from 13:55 to 16:02 local time, reducing the frame dimensions to 960 x 576px. According to question 27 in the interrogation report (BAP - Berita Acara Pemeriksaan) of Muhammad Nuh Al-Azhar, the dimensions should have been 1920 x 1080 px.
Analysis
Muhammad Nuh Al-Azhar's deliberate downscaling of CCTV 2 footage from 13:55 to 16:02 local time had significant forensic implications. By reducing the frame dimensions to 960 x 576px, crucial details that could have been captured in the original high-resolution footage were obscured. This intentional manipulation raises questions about the integrity of the evidence presented in court and suggests potential ulterior motives behind altering the footage.
The original CCTV 2 footage should have captured remnants of the coffee consumed by Mirna Salihin, which was brought from table 54 by eyewitness Devi Siagian. However, by downscaling the footage, Muhammad Nuh Al-Azhar effectively hindered any analysis of the coffee residue, making it difficult to determine its composition or any potential contaminants, such as cyanide. This manipulation undermines the ability to gather critical evidence related to the case and could potentially impact the accuracy of forensic analyses.
The impact of downscaling on CCTV footage, particularly in cases involving suspected poisoning with substances like cyanide, is crucial for forensic pathologists in several ways. Firstly, downscaling can significantly degrade the quality and clarity of the footage, making it more challenging for pathologists to observe subtle details and nuances in the subject's behavior and physical condition. This reduction in visual fidelity may hinder the accurate identification and interpretation of specific symptoms or reactions exhibited by the individual after consuming the alleged poisoned substance.
Secondly, downscaling may obscure important visual cues that could provide valuable insights into the individual's physiological responses to cyanide poisoning. For example, changes in facial expression, skin tone, or bodily movements that typically accompany cyanide exposure may be less discernible or entirely lost due to the diminished resolution and frame rate of the footage. As a result, pathologists may struggle to assess the severity of the victim's condition or determine the presence of characteristic symptoms associated with cyanide poisoning, such as respiratory distress, convulsions, or loss o

00:00Australian resident Jessica Wongso has been charged with the murder of Minis Alihin.
00:08Police allege she poisoned her friend by adding cyanide to her coffee.
00:12Jessica is like a devil.
00:15Deep inside is something like evil.
00:18It is said that the trial of the century is true.
00:27Evidence 9.
00:28CCTV video 2 from 1355 to 1602 local time was reduced in frame dimensions T0960 by 576
00:38pixels.
00:39Mohammed Nah Al-Azhar deliberately performed downscaling on CCTV 2 footage from 1355 to
00:451602 local time, reducing the frame dimensions to 960x576px.
00:52According to Question 27 in the interrogation report, BAP Berita Akar Pemarikson, of Mohammed
00:59Nah Al-Azhar, the dimensions should have been 1920x1080px.
01:04Analysis Mohammed Nah Al-Azhar's deliberate downscaling
01:08of CCTV 2 footage from 1355 to 1602 local time had significant forensic implications.
01:16By reducing the frame dimensions to 960x576px, crucial details that could have been captured
01:23in the original high-resolution footage were obscured.
01:26This intentional manipulation raises questions about the integrity of the evidence presented
01:31in court and suggests potential ulterior motives behind altering the footage.
01:37The original CCTV 2 footage should have captured remnants of the coffee consumed by Mirna Salihin,
01:42which was brought from Table 54 by eyewitness Devi Sejian.
01:46However, by downscaling the footage, Mohammed Nah Al-Azhar effectively hindered any analysis
01:51of the coffee residue, making it difficult to determine its composition or any potential
01:56contaminants, such as cyanide.
01:59This manipulation undermines the ability to gather critical evidence related to the case
02:04and could potentially impact the accuracy of forensic analyses.
02:08The impact of downscaling on CCTV footage, particularly in cases involving suspected
02:14poisoning with substances like cyanide, is crucial for forensic pathologists in several
02:19ways.
02:20Firstly, downscaling can significantly degrade the quality and clarity of the footage, making
02:25it more challenging for pathologists to observe subtle details and nuances in the subject's
02:30behavior and physical condition.
02:33This reduction in visual fidelity may hinder the accurate identification and interpretation
02:38of specific symptoms or reactions exhibited by the individual after consuming the alleged
02:43poisoned substance.
02:44Secondly, downscaling may obscure important visual cues that could provide valuable insights
02:49into the individual's physiological responses to cyanide poisoning.
02:54For example, changes in facial expression, skin tone, or bodily movements that typically
02:59accompany cyanide exposure may be less discernible or entirely lost due to the diminished resolution
03:05and frame rate of the footage.
03:07As a result, pathologists may struggle to assess the severity of the victim's condition
03:12or determine the presence of characteristic symptoms associated with cyanide poisoning,
03:17such as respiratory distress, convulsions, or loss of consciousness.
03:21Moreover, the distortion or loss of critical visual information resulting from downscaling
03:27could impede the accurate reconstruction of events leading up to and following the alleged
03:31poisoning incident.
03:33Pathologists rely on comprehensive and unaltered video footage to establish timelines, identify
03:38potential sources of contamination, and correlate observed symptoms with specific actions or
03:44exposures.
03:45However, when the footage is compromised by downscaling, these forensic analyses become
03:50inherently more challenging, and the reliability of any conclusions drawn from the evidence
03:55may be called into question.
03:58Furthermore, downscaling may limit the forensic pathologist's ability to differentiate between
04:03natural physiological responses and those induced by external factors such as poisoning.
04:09Without access to high-quality, unaltered footage, pathologists may struggle to conclusively
04:14attribute observed symptoms or abnormalities to cyanide poisoning, potentially leading
04:19to inconclusive or speculative findings.
04:22This limitation underscores the critical importance of preserving the integrity and fidelity of
04:27CCTV footage in forensic investigations, particularly in cases involving allegations of
04:33poisoning or other criminal activities.
04:35Therefore, the impact of downscaling on CCTV footage presents significant obstacles for
04:41forensic pathologists tasked with analyzing suspected cases of cyanide poisoning.
04:46By degrading the quality, clarity, and reliability of the visual evidence, downscaling diminishes
04:52the effectiveness of forensic analyses and undermines the ability to accurately assess
04:57and interpret the individual's physiological responses to alleged poisoning events.
05:03As such, efforts to preserve the integrity and authenticity of video evidence are paramount
05:07in ensuring the validity and credibility of forensic investigations and legal proceedings.
05:13The motive behind Mohammed Na'alaza's actions warrants scrutiny.
05:17By manipulating the CCTV2 footage, he may have sought to conceal crucial details that could
05:22have implicated or exonerated individuals involved in the case.
05:27This raises concerns about the objectivity and impartiality of the investigation process,
05:32as well as the reliability of the evidence presented in court.
05:36Moreover, the forensic impact of downscaling the CCTV2 footage extends beyond the immediate
05:42implications for the Jessica Wongso case.
05:45It underscores the broader issue of tampering with digital evidence and the challenges it
05:49poses for forensic analysis and legal proceedings.
05:54Such manipulations not only compromise the integrity of the evidence, but also erode
05:58public trust in the justice system.
