TO THE REPUBLIC OF TURKEY ISTANBUL CHIEF PUBLIC PROSECUTOR’S OFFICE

(Bureau of Terror and Organized Crimes Investigation / To Be Submitted to the Relevant Investigation File)

SUBJECT: Request for the forensic examination of mechanical and electronic data logs from commercial telemetry systems and post-mix (beverage dispensing) units located at and around the scene of the incident, within the scope of forensic evidence and timeline determination.

STATEMENTS:

In order to determine the precise micro-second timing of the explosion (timestamp correlation), establish the directional path and impact radius of the blast wave, and evaluate environmental physical effects, the technological and industrial infrastructure data from businesses operating within the affected perimeter must be incorporated into the case file.

Commercial beverage dispensers (including Coca-Cola, Pepsi, and related post-mix and telemetry-enabled smart dispensing units) utilized in these establishments (concession stands, restaurants, stadium retail points, and surrounding facilities) operate via closed pressure systems and integrated printed circuit boards (PCBs) that maintain continuous operational records. Due to their mechanical design and data-logging architecture, examining the following points will provide direct technical utility to the investigation:

1. Data Logging and Architecture:

These systems continuously monitor CO₂ carbonation pressure, water line inlet pressure, solenoid valve cycles, and electrical supply stability at second or sub-second intervals. In the event of an anomaly or disruption, error codes (Event Logs) are written to local non-volatile storage (EEPROM/NAND) and concurrently transmitted to centralized cloud-based telemetry servers.

2. Blast Wave Dynamics and Physical Impact Verification:

The blast-induced overpressure wave produces electrical surges across local distribution grids and creates hydraulic hammer effects or rapid pressure drops (Pressure Drop) across incoming municipal water lines and gas regulators. Any sudden mechanical displacement or ratio drift caused by the shock wave is recorded by system diagnostic registers as an operational fault or supply failure.

3. Cloud and Telemetry Network Infrastructure:

Current-generation commercial dispensers utilize integrated M2M/IoT cellular modules to transmit persistent network signals (“heartbeats”) to distributor telemetry hubs (Coca-Cola İçecek / PepsiCo infrastructure). The precise timestamp marking cellular disconnection, power termination, or mechanical failure yields verifiable technical data that can be correlated with regional seismic arrays and base transceiver station (CDR) logs.

REQUEST AND CONCLUSION:

In accordance with the technical specifications outlined above, I respectfully request the following measures:

  1. Identification of the serial numbers and hardware models of post-mix beverage dispensing units located within the blast perimeter and adjacent commercial venues,
  2. Issuance of official judicial requests to the relevant technical divisions of Coca-Cola İçecek A.Ş. and PepsiCo Turkey, demanding time-stamped (NTP/UTC synchronized) server logs documenting power disruptions, pressure losses (Low Pressure), valve faults, and cellular disconnections for the specified date and operational time window,
  3. Retrieval of network transmission records from cellular service providers regarding the final data packet transmissions of the M2M/IoT SIM cards embedded within these units,
  4. Subpoena of post-incident on-site inspection forms, repair tickets, and component replacement logs filed by authorized field service personnel for the units in question, and their formal inclusion in the case file.

Respectfully submitted for requisite judicial action.

    My name is Fehim Calgav. I was born on January 19, 1969, and I am 1.76 meters tall. I am the son of Sema Calgav and Yaşar Calgav. Our family originates from the Lausanne Exchange of Populations. There is no Georgian ancestry in our family tree; we are a true exchange family. I started my education at Feyzullah Primary School. I attended Maltepe High School for middle school and completed my high school education in the 2nd year of Maltepe High School. I come from a family tradition of naval officers. Our family consists of Yaşar Calgav, Sema Calgav, and three siblings: my sisters Özlem Calgav Güngör and Özden Calgav Uçar, and myself. Contact: red.lion.king.fehim.calgav@gmail.com

    Yes, there is an average. It is called the basic reproduction number (R0). R0 is the average number of people one infectious person infects over the course of their illness, in a population where no one is immune and no measures are in place.
