The vehicle was found submerged in the water at the bottom of a 150-metre cliff close to a highway that approaches the park, reported a Thai-language online newspaper in the US on Wednesday.
Postgraduate students Thiwadee Sangsuriyarit, 24, and Bhakapon Chairatanatongporn, 28, of South Florida University, went missing late last month on their way to the park. They were reported missing when they did not return to their hotel.
Thiwadee’s mother said she was hoping for a miracle and praying that her daughter was safe.
Bhakaphon’s mother said that her son, nicknamed “Golf”, had gone to study engineering at the university about 18 months ago. He was due to graduate in December and the family was planning to attend the graduation ceremony in the US.
She said she usually warned her son not to drive in the US as he was not used to the roads. Now she said she was too sad to even look at his photos.
Both families were waiting for the visas to go to the US.Siam Media online reported that California Highway Patrol had told Thai Consul General Tanee Sangrat that there was no space in the area for a helicopter to land safely.
The only way to access the accident site was by boat, the online newspaper said, but because of the melting snow and strong current, it would be too dangerous.
