Geylang Bahru family murders (1979)

On the morning of 6 January 1979, four children from the Tan family were violently murdered in their Housing and Development Board (HDB) flat. The four children, aged between 5 and 10 years old, were found slashed to death in the bathroom of their one-room flat in Block 58 Geylang Bahru. Their parents, Mr and Mrs Tan Kuen Chai, were at work when the murders took place.1 The murders remain unsolved.2

The victims were Tan Kok Peng, 10, Tan Kok Hin, 8, Tan Kok Soon, 6, and their sister, Tan Chin Nee, 5. The three boys studied at Bendemeer Road Primary School, while their sister attended a nearby PAP kindergarten.3

At 6.35 am, the Tans left their flat to transport students to school in their mini-bus, which they operated together.4 Their children were sleeping when they left. Mrs Tan telephoned home at 7.10 am to wake them up as usual, but received no response after three separate calls. She then asked one of her neighbours to help wake them up. The neighbour knocked on the door of their flat, but also received no response.5

The Tans arrived home after 10 am and Mrs Tan found the slashed bodies of her children in the bathroom. The four children were found in T-shirts and pants, and all four had slash wounds on their heads. Slash wounds were also found on Chin Nee’s face and Kok Peng’s right arm was almost severed.6 According to the pathologist’s report, each child had a minimum of 20 slash wounds on his or her body.7

The police concluded that the murders were premeditated and that the perpetrator or perpetrators had taken care to avoid leaving incriminating evidence behind.8 However, there were bloodstains in the kitchen sink and the killer or killers were believed to have cleaned themselves before leaving the flat.9 There was no evidence of forced entry, and the flat was not ransacked nor were there any items reported missing. The murder weapons, believed to be a chopper taken from the kitchen of the flat as well as a dagger, were not found.10

The investigation into the murders was conducted by the Criminal Investigation Department’s Special Investigation Section. They did not establish a definitive motive but acknowledged the possibility of the killings being motivated by revenge.11 Mrs Tan’s brother told the media that the murders could have been related to an illegal tontine scheme, and police pursued the possibility of the killer being a discontented gambler. However, that angle of investigations did not lead to the murderer and the Tans told the media that they had not offended anyone.12

The police also believed the murderer or murderers had intimate knowledge of the Tans and their background, as they were apparently aware that Mrs Tan had undergone sterilisation after the birth of her last child.13 In addition, the Tans received a Chinese New Year card two weeks after the murder, which may or may not have been a hoax. The card showed happy children at play and taunted them with the words “now you can have no more offspring ha-ha-ha” and was signed “the murderer” in Mandarin. The sender of the card also appeared to have intimate knowledge of the family as they addressed the Tans by their nicknames, “Ah Chai” and “Ah Eng”.14

On 7 January 1979, homicide investigators questioned two women in connection to the murders but later released them, not commenting if the women were of help.15 Despite interviewing over 100 of the Tan family’s neighbours and public appeals for witnesses, the police had difficulties obtaining useful information.16 Residents in the area claimed a witness had seen Chin Nee struggling with a man from his flat in another block, but the witness could not be located.17 The children’s parents were also questioned by police.18

A witness told Chinese newspapers he saw a couple, one of them bloodstained, leaving the scene of the murder, but police investigations later revealed it to be a hoax.19 One of the Tans’ neighbours, 68-year-old Yam Yin Tin, said she usually sat along the common corridor to watch children playing, and would have seen anyone coming and going from the Tan family’s flat. However, on the morning of the murders, she was washing her hair and did not see anyone entering or leaving the Tans’ flat.20

A taxi driver from Toa Payoh later reported that a man in his 20s who walked with a lurch had boarded his taxi near Block 96 along Kallang Bahru Road, near the location of the murder, at about 8 am that morning. The taxi driver said that the man had bloodstains on the left side of his body and carried a knife that “banged against the taxi door” when he alighted at Lavender Street. Mr Tan matched the taxi driver’s description to a neighbour of his, a young man who visited the family’s flat almost daily to use their phone, and who was known as “Uncle” to the whole family. In a police line-up, the taxi driver picked out the neighbour as the man who had boarded his taxi. However, the neighbour was released after two weeks due to a lack of evidence connecting him to the murders. The man, who was Malaysian, later moved out of Block 58 with his sister.21

The children were buried at Choa Chu Kang Cemetery on 7 January 1979 together with their schoolbags, books and toys. Mrs Tan passed out several times as her children were being placed in their respective coffins.22 The murderer or murderers were never caught and brought to justice.23 Soon after the tragedy, the Tans gave up their mini-bus operation and found work at a plastic bag machining firm.24

A year after the gruesome murders, the Tans were featured in The Straits Times and referred to their home as “four walls of emptiness”. The Tans also registered with the Social Welfare Department, hoping to adopt two children.25 Eventually, Mrs Tan underwent a sterilisation reversal operation and was able to conceive again. On 30 December 1983, at the age of 35, she gave birth to a baby boy.26

The Straits Times noted the brutality of the murders and described them as the most inhuman in Singapore’s crime history.27 The newspaper also described police sources as being shaken and sickened by the murders.28
