EVIDENCE 15: PROSECUTORS MANIPULATING THE CONTENT OF FLASH DRIVE

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 15: FOLDERS CCTV 15 AND CCTV 16 SUDDENLY ADDED TO FLASH DRIVE IN PROSECUTOR'S POSSESSION

A digital forensic analysis of the flash drive held by the prosecutor revealed several important details. First, when factual witnesses Marlon Napitupulu and Agus Triyono testified in court on July 20, 2016, the flash drive contained only 11 CCTV folders, with folders CCTV 15 and CCTV 16 missing. However, when Jessica was presented as the defendant, the number of CCTV folders increased to 13, as previously mentioned. This indicates that there was a modification or change to the contents of the flash drive.

Furthermore, during the trial when Jessica Kumala Wongso was presented as the defendant on September 28, 2016, the flash drive played by the prosecutor again showed 13 CCTV folders, containing files from CCTV cameras 1 to 9, as well as CCTV 15, CCTV 16, CCTV 17, and CCTV 18. What is noteworthy is the modification dates of the folders, where most folders have a modification date of January 12, 2016, except for folder CCTV 15, which has a modification date of July 21, 2016, and folder CCTV 16, which has a modification date of July 26, 2016.

The change in modification dates for folders CCTV 15 and CCTV 16 is suspicious because it is inconsistent with the modification dates of the other folders. This indicates that there was manipulation or editing done to these two folders after the modification dates of most of the other folders. Such editing suggests that the authenticity and integrity of the digital evidence have been compromised.

The motive could be to undermine the defense's ability to respond effectively to the evidence. The sudden appearance of two new folders could catch the defense off guard, limiting their time to analyze and respond to the new evidence. This could create an imbalance in the courtroom, favoring the prosecution by putting the defense at a strategic disadvantage.

The inconsistency in modification dates is also a critical factor suggesting intentional manipulation. Most folders have a modification date of January 12, 2016, but folders CCTV 15 and CCTV 16 were modified in July 2016. This discrepancy indicates that these folders were added or altered much later, likely with a specific purpose in mind. This could be an attempt to fabricate or alter evidence to fit a desired narrative, casting doubt on the integrity of the digital evidence and the intentions behind its presentation.

Moreover, the timing of the addition of these folders raises questions about the integrity of the judicial process. The fact that the folders appeared just before Jessica's tria
