Tong Ching Man (唐清雯,[1]tang CHING-win; 17 October 1970 – 21 April 1995) was a 25 year old female Hong Kong national executed in Singapore for drug trafficking.

[8] At 5am on the morning of 16 December 1988, Central Narcotics Bureau officer Teo Chin Seng attempted to interrogate Lam via a Cantonese interpreter, however he exercised his right to silence and refused to answer any questions.

[5][11] Lam's defence was he was asked to carry blocks of tranquillizers to Belgium by a man named "Ah Keung" in order to avoid paying custom duties then sell on the grey market, and would be paid a fee of HK$15,000 for doing so.

Regarding the drugs she was caught with, Tong claimed to have never even seen heroin before, and when asked to clarify how traces of opioids were found in a urine sample she gave shortly after her arrest, she explained that she was prescribed a cough medicine in Hong Kong that may have contained codeine.

The Prosecution also dismissed Tong's claim of innocence by questioning why an 18 year old waitress from Hong Kong (who had never even applied for a passport before) would suddenly decide to go on a vacation to Belgium for only 3 days, whereas a more likely explanation pointed to her intentionally working as a drug mule instead.

[13] On 19 August 1993, Tong and Lam were both found guilty as charged and sentenced to death for importing 3 kilograms of pure heroin into Singapore, contrary to Section 7 of the Misuse of Drugs Act.

[14] The judge remarked that the elaborate manner of covertly transporting "tranquilizers" coupled with the large monetary reward offered to Lam seriously undermined his testimony, which in addition to the fact he did not mention this explanation in his initial statement to police compelled the court to reject his account.

The judge also dismissed Tong's attempt to portray herself as a naive and gullible teenager, as her own testimony described her fending for herself in a tough working class district of Hong Kong from a very young age, and she would therefore have been highly unlikely to agree to transport 18 blocks of an unknown substance onto an airplane under incredibly suspicious circumstances.

[3][15] In September 1994, the British Government lodged a letter with the Singaporean authorities appealing for clemency on Tong's behalf[16](Hong Kong was a United Kingdom Overseas Territory at the time).

[17] Tong converted to Christianity while on death row, and had shared in a letter to her close friend Man Yuen-fun how her faith was helping her, writing: "The Holy Spirit is now filling up my heart.
