A 70-year-old man and his 92-year-old elderly mother were both found dead at a Tampines HDB unit on the morning of 22 October.
The Singapore Police Force said that they received a call for help at about 11.56am.
When the police arrived at the scene on the 11th floor of Block 285 Tampines Street 22, the two deceased were found lying motionless.
They were subsequently pronounced dead at the scene.
Shin Min Daily News reported that the neighbours smelled a foul stench emanating from the flat, and that they started noticing it about a week ago.
However, they had initially thought that the smell came from other residents’ cooking and didn’t think too much of it.
According to the police’s preliminary investigations, no foul play is suspected and police investigations are underway.
