  • Panthep reveals new scientific evidence arguing Tangmo's injuries did not come from a boat propeller
  • Investigation points out seven fabricated elements and tampered timelines in the official case files
  • GPS and CCTV analysis confirm only five people were aboard the boat at the critical time
  • Photos of actress Kwan Usamanee's boat were mistakenly or intentionally mixed into the timeline evidence

Panthep Pourpongpan has publicly presented a new set of scientific evidence concerning the photographs and physical injuries documented in the controversial death case of actress Nida 'Tangmo' Patcharaveerapong. According to his analysis, the wounds found on the body could not possibly have been caused by a boat propeller due to their specific dimensions—measuring 2 centimeters, 0.8 centimeters, and 3 centimeters—as well as puncture wounds behind the right knee exposing fatty tissue, which contradict standard propeller trauma patterns.

Furthermore, questions were raised regarding leaves found all over the victim's head in water devoid of floating foliage, alongside bruises on both knees suggesting she may have been crawling or escaping from an unknown threat rather than falling backward into the deep water while urinating. He noted similarities to past cases consulted with Dr. Pornthip Rojanasunan regarding concealment methods involving shallow water pressure before moving bodies to deeper areas.

Regarding the timeline on the night of the incident, Panthep cross-referenced mobile phone data from Tangmo, Gatick, Dada, Dada's brother, and Kwan Usamanee. The analysis indicated that Tangmo's last active phone usage occurred at 20:36, after which subsequent messaging and phone activity showed signs of manipulation. At least seven fabricated points were identified, including manipulated timestamps on Gatick's solo photos near the Rama VIII Bridge to match CCTV footage timelines near the San Phra Phut and Phra Ram 8 areas.

This analysis highlights the critical role of digital forensics, metadata verification, and GPS tracking in modern legal investigations. Discrepancies between physical timestamps and digital records often serve as key indicators for uncovering flaws or inconsistencies in official investigative testimonies.

"The wounds make us believe it was not caused by a boat propeller because there were various injuries, and the death was definitely not caused by falling backward into deep water."

Another major breakthrough involved photographs taken by Dada's brother on February 24 at 20:32 near the Rama VIII Bridge, which were mistakenly cited in the case file. Upon investigation, the vessel belonged to actress Kwan Usamanee, who confirmed her presence on the boat that night with six passengers heading toward Wat Arun by 21.11, effectively disproving certain timeline claims presented in the official investigation.
