Key Intelligence Findings
AIS Blackout Confirmed — 3 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where GARY L.HOLMAN was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
GPS Spoofing — 2 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 2,261 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Evasion Navigation — 19 Zigzag Events
Erratic course-over-ground patterns up to 156.2° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
