Now emerging from a coma yet still unable to speak, Matthias Stefan Koch, 38, has been confined to a bed at Songklanadarind Hospital in Had Yai since October 25 last year when he sustained serious injuries in a fall at Had Yai airport.
Since then, the bill for his hospital treatment has accumulated to 1.8 million, while the cost of flying him home to Germany is estimated at 400,000 baht.
Because he is unable to speak, nobody knows precisely how Mr Koch incurred the injuries. He had a history of mental illness before he was found after climbing and falling from an elevated passageway in an air-conditioning control room at Had Yai airport around 9pm.
He was due to fly to Germany and his home town of Scheblitz the following day. Traces of sleeping pills were found in his blood.
Parinya Bantito, who heads the hospital's social welfare department, said that Mr Koch was a frequent visitor to Had Yai who enjoyed the life there and stayed at the same guesthouse.
As with other embassies, the German embassy has a policy of not paying hospital bills incurred by its travelling citizens.
With Mr Kock's debt growing and with no likelihood of help coming from any other source, after 10 months the director of the hospital has opened a special account for donations to help meet costs and help send Mr Koch home.
The account name is slightly different, however. People wishing to help should deposit donations with Siam Commercial Bank Account No. 565 4 39248 5 in the name of Kock Matthias Stefen. Khun Parinya can be reached by telephone at 074 455000.
