SINGAPORE - He resented his father and has not seen him for the past two years. But each time Ken Ong did see his father, he would blame him for not supporting him while he was growing up.
Reporters from Lianhe Wanbao managed to speak to the father of Ong, the 37-year-old man who reportedly stabbed himself after slashing his wife, Madam Karen Koh, 39, at their Yuan Ching Road condominium on Friday morning.
Their Filipino maid, Ms Jamelarin Jasmen Corpuz, 37, was also attacked by Ong when she tried to intervene.
Ong's father, Mr Ong De Ying, told the Chinese evening daily that his son had moved out from their 2-bedroom rented unit at Toa Payoh Lorong 5 over a decade ago.
Although his son would visit him once every few years, their relationship was strained. They hardly kept in touch and had nothing to say to each other, revealed Mr Ong.
"He blames me for leaving him with his grandmother after my divorce," said the 69-year-old Ong.
In his email titled 'Final Note', the younger Ong wrote about coming from a divorced family and "how much hurt it can give to a kid". Ong had no siblings, according to Lianhe Wanbao.
The newspaper also reported that Mr Ong was unaware of his son's marriage when he last saw him two years ago. He only knew that he was living with a woman in Jurong.
He told Lianhe Wanbao that his son stayed for only five minutes and left without speaking a word when he last visited him. He also said that he had never seen his son's girlfriend before.
So it comes as no surprise when Mr Ong, who is currently in hospital due to heart problems and high blood pressure, said he had no idea his son had died until two plainclothes police officers told him about the news on Friday night.
Ong and his wife succumbed to injuries when they were taken to National University Hospital (NUH). Ms Corpuz was also taken to NUH and is reportedly in a stable condition.
