Singapore is a pretty safe city, but every now and then, a murder surfaces and we’re shaken to our core.

Famous true crime cases in Singapore
1. The curry murder
In 1984, Nagaratha Vally Ramiah made a police report about her missing husband, Ayakanno Marimuthu. Three years later, the case became warm when an informant notified the police of what transpired. It’s believed Marimuthu was bludgeoned with an iron rod, then chopped up and cooked in curry.
However, the eight suspects, including Ramiah, her mother, her three brothers and their wives, were released due to a lack of evidence. Up till today, the remains, the murder weapon and the pot are still missing.
2. Geylang Bahru family murders

Probably one of the heinous crimes in Singapore, the Geylang Bahru family murders took place on the unassuming morning of 6 January 1979. Mr and Mrs Tan Kuen Chai ran a school bus service transporting students and left for work as usual. Mrs Tan called home to wake her kids up for school but no one picked up. Next, she called her neighbour to check up on them but no one responded either. When they returned home, to their shock, they found all four kids dead in the bathroom with at least 20 slash wounds on each child. The victims were Tan Kok Peng, 10; Tan Kok Hin, 8; Tan Kok Soon, 6; and their sister, Tan Chin Nee, 5.
It’s believed that the murders were premeditated and the murderer had personal knowledge of the Tan family. Two weeks after the murder, they received a chilling CNY letter that said, “now you can have no more offspring ha-ha-ha”; it was signed “the murderer” in Mandarin. A painful taunt pointing to the fact that Mrs Tan had been sterilised after giving birth to her daughter. Unfortunately, the tragic murder remains a cold case in Singapore.
3. Toa Payoh ritual murders
Riddled with human scarification, sexual abuse and blood rituals, the Toa Payoh ritual murders shook Singapore. The murder investigations of Agnes Ng Siew Heok and Ghazali bin Marzuki led the police to the mastermind Adriel Tan and his two accomplices: his wife Catherine Tan Mui Choo and his mistress Hoe Kah Hong.
After discovering Ghazali’s body between blocks 10 and 11 in Toa Payoh on 7 February 1981, the police followed the bloody trail which brought them to Adriel’s flat. When they stepped in, they found religious idols and blood stains on the floor.
Adriel had been posing as a medium for years and tricked his clients into sleeping with him as part of the cleansing process. Chatherine and Kah Hong were taken by his “special powers” and abetted in the murder of said victims. All three were found guilty and hanged on 25 November 1988.
4. McDonald’s boys case
It’s hard to imagine people can actually go missing on our little island. But that’s what happened to two 12-year-old boys on 14 May 1986. Toh Hong Huat and Keh Chin Ann disappeared into thin air. Chin Ann was last seen leaving school to shop while Hong Huat asked his mum if he could meet a friend to go to school. She assumed he was meeting Chin Ann.

When both boys didn’t turn up for class, the search began. On 27 August 1986, someone reported sightings of the missing boys at Pulau Ubin after canvassing the island, nothing came out of it. The searches extended to neighbouring countries as well. Even fast food chain McDonald’s put its weight behind the search by offering a $100,000 reward for any information – hence the name of the case.
There were many theories as to what happened. Some speculated that they were kidnapped by a human trafficking syndicate and transported to Thailand. Sadly, the case remains unsolved – the boys would be aged 47 now.
5. Yishun triple murder
Strange things sure seem to happen in Yishun. What started as a trivial argument between Wang Zhijian and his girlfriend Zhang Meng ended in the deaths of her and her daughter. Zhang Meng craved crab for dinner but Zhijian refused to spend the money when they just had it last week. Upset, she hurled hurtful words at him.
The relationship was tumultuous, to say the least, but this incident was the last straw for him. After committing the murders, he went to the other room to kill a mother and daughter duo who lived in the rental flat. The mum tried to escape from the kitchen window but Zhijian chopped off her hands as she held onto the bamboo poles and she fell to her death. Fortunately, the daughter survived the entire ordeal.
To make things even more bizarre, Zhijian was always caught by the press with a sinister grin on his face. He eventually was sentenced to death, despite appealing to the court by the way of his mental health condition.
