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.
00:15Jessica is like a devil.
00:17Deep inside is something like that, evil.
00:22It is said that the trial of the century is true.
00:29Evidence 13, CCTV 3 footage was deliberately converted from color to grayscale right when
00:35Myrna Salihin arrived at Olivier Cafe at 1718 local time.
00:40This evidence showed that the CCTV 3 footage was deliberately converted from color to grayscale
00:45right when Myrna Salihin arrived at Olivier Cafe at 1718 local time.
00:51Based on the available information, the following was a digital forensic analysis related to
00:56this case.
00:58The CCTV 3 video was split into two files, CH03-15.55-17.18.mp4, color video, and CH03-17.18-18.45.mp4,
01:14grayscale video.
01:15This change occurred precisely at the time of Myrna Salihin's arrival, which was very
01:19suspicious given the importance of visual information during that period.
01:24The video starting at 1718 local time was converted from color to grayscale, removing
01:29color information present in each YUV channel, according to its metadata in the statement
01:34by Muhammad Nuh Al-Azhar.
01:37This conversion resulted in the loss of crucial color information related to objects, such
01:42as the coffee cup and Myrna Salihin's skin tone.
01:45In the examination report, BAP, presented by Muhammad Nuh Al-Azhar, the metadata of
01:50the CCTV 3 video indicated that the video had a YUV color space, suggesting that the
01:56original video was recorded in color format.
01:59The presence of the YUV color space in the metadata strengthened the evidence that the
02:03video was initially in color before being converted to grayscale.
02:08This loss of visual information had serious forensic implications.
02:12For instance, at 1730 local time, Devi Siajian carried the coffee cup from table 54 to the
02:19cocktail bar.
02:21The color information of the coffee cup could have indicated any color changes allegedly
02:26caused by hazardous substances like cyanide.
02:29Additionally, at 1728 local time, Myrna was taken out of the cafe in a wheelchair.
02:36The color of Myrna's face and arms could have provided clues about her physical condition,
02:40such as signs of poisoning or allergic reactions.
02:43This color manipulation destroyed the video's credibility as evidence, suggesting an attempt
02:49to conceal important information.
02:52This action was carried out by Muhammad Nuh Al-Azhar and Christopher Harriman Rianto,
02:56who should have been responsible for maintaining the integrity of every bit of information
03:00in the video.
03:02This manipulation showed a serious breach of professional ethics and raised doubts about
03:06their analytical results in this case.
03:09The manipulation of the CCTV 3 footage was a very critical act.
03:13The removal of color information from the video was highly detrimental because such
03:17information was essential for analyzing the volume and color of the coffee as well as
03:22Myrna Salihan's physical condition.
03:25This act indicated an effort to hide crucial evidence that could have revealed the actual
03:29facts of the incident.
03:31The video metadata indicating the use of the YUV color space suggested that the video was
03:36originally recorded in color, which should have provided complete visual information
03:41to ensure justice and the integrity of the legal process, a re-evaluation of the existing
03:46evidence and decisive action against the ethical violations by the involved digital
03:50forensic experts were necessary.
03:54Forensic impact explanation, the deliberate conversion of the CCTV 3 video from color
03:58to grayscale has significant forensic implications.
04:02The color information in the original footage is vital for accurately analyzing and understanding
04:08events captured by the camera.
04:10When this information is removed, critical details are lost, which can severely impact
04:15the investigation.
04:17For instance, the color of objects such as the coffee cup and the skin tone of individuals
04:22can provide essential clues regarding the presence of substances or the physical condition
04:27of the individuals involved.
04:28The absence of this color data undermines the ability to draw accurate conclusions from
04:33the video evidence.
04:35The manipulation of the video raises questions about the integrity of the evidence.
04:40By altering the original footage, the credibility of the evidence is compromised.
04:45This act of tampering suggests an attempt to conceal important information that could
04:50be crucial to the case.
04:52In a forensic investigation, maintaining the authenticity of evidence is paramount.
04:57Any alterations can cast doubt on the entire body of evidence, making it challenging for
05:01investigators to establish a clear and accurate narrative of events.
05:06This manipulation not only affects the current case, but also sets a dangerous precedent
05:11for future investigations.
05:14The presence of YUV color space metadata in the original video indicates that the footage
05:18was initially recorded in color.
05:21This metadata serves as a digital fingerprint, verifying the original format and providing
05:26a basis for identifying any unauthorized changes.
05:30The conversion to grayscale, therefore, represents a deliberate act of altering the evidence.
05:36The forensic impact of this manipulation extends beyond the loss of visual information.
05:41It highlights a breach of protocol and ethical standards by those responsible for preserving
05:46the integrity of the evidence.
05:48This breach can lead to questions about the reliability of other evidence handled by the
05:52same individuals.
05:54The loss of color information has practical implications for the forensic analysis.
05:59For instance, the color of the coffee cup could indicate contamination by hazardous
06:03substances or not, which may not be detectable in grayscale footage.
06:08Similarly, the color changes in a person's skin can provide vital clues about their health
06:13and physical reactions at the time of the incident.
06:16Without this information, forensic experts may be unable to accurately assess the situation,
06:21potentially leading to incorrect conclusions and hindering the pursuit of justice.
06:26The grayscale footage limits the scope of forensic analysis and diminishes the overall
06:31effectiveness of the investigation.
06:33Lastly, the ethical implications of manipulating video evidence cannot be understated.
06:40Those responsible for altering the footage, Mohamedna Al-Azhar and Christopher Harriman
06:44Rianto, violated their professional duty to maintain the integrity of the evidence.
06:50This action demonstrates a significant breach of trust and raises serious concerns about
06:55the conduct and credibility of the forensic experts involved.
06:59For the legal system to function effectively, it is crucial that evidence is handled with
07:03the utmost care and professionalism.
07:05Addressing this ethical violation is essential to restoring confidence in the forensic process
07:11and ensuring that justice is served in this case and future investigations.
