SINGAPORE - The man involved in the Yuan Ching Road deaths on Friday morning had apparently sent an e-mail to the media detailing his grievances with his wife and the couple's maid.
The e-mail had the subject header "Jurong Murder" and a headline "Final Note". It was sent to various newsrooms which received it at 8.11am.
Police received a call for help at Park View Mansion at 7.56am. The Singapore Civil Defence Force was alerted to the incident at 8am, and dispatched three ambulances to the condominium.
When police officers arrived at 9D Yuan Ching Road, they found a 37-year-old Filipino maid injured and bleeding, with wounds to her face.
Shortly after, officers found a 37-year-old Singaporean man and his 39-year-old wife - a Malaysian permanent resident - injured inside a unit in the condominium.
It is believed that they had got into a dispute and their maid was injured when she tried to intervene.
All three were sent to the National University Hospital. The couple later died.
The lengthy e-mail was signed by a man who identified himself as Mr Ken Ong.
Among other things, he said he had been living with his wife for 12 years but that the marriage was unhappy and they were in the midst of a divorce.
He talked about how he had gone back to study at the Building and Construction Authority and that it had been stressful.
"Study at 36 years old after being away from studies about 18 years and especially wanted to fight with the elites from China to be top of the cohort and "A" student is not a joke," he wrote.
He also said his wife had a young son, whom he loved a lot and hoped would be adopted and "brought up in a proper home and...taught the proper manners and ways to be a man".
He also said he did not agree to keeping the maid, alleging she did not perform her duties well, but said that his wife wanted to keep her.
Mr Ong had shared the note on what appears to be his Facebook page as well. Previous posts on his account from as early as November last year suggested that he had intentions to do something drastic.
On Dec 17, he wrote: "One more thing done, 2 more to go before i do what i should had done long ago."
Police investigations are ongoing.
