The crash was so loud that she immediately knew someone was killed.
Madam Xu Xiao Yun, 52, a cook at nearby coffee shop 568 Kopitiam, dashed out of her stall to the road and saw the body lying in a pool of blood.
She said: "I kept shouting 'Auntie, auntie!', but there was no response."
The accident took place at around 5am yesterday at the junction of Serangoon Road and Beatty Road.
It is believed that the victim, Miss Chen Meiping, a 50-year-old nurse, was on her way to Xin Wang Coffee And Tea House, which is across the road from 569 Kopitiam to get complimentary newspapers when she was knocked down by a car.
The impact was so powerful that witnesses claim her body ended up several metres away.
Said Madam Xu: "Her body flew past the foodcourt and two shops. I knew that there was no way she could be saved."
The driver, a male in his 30s, immediately called for an ambulance, while a family friend of the Chen family who happened to be at the scene ran to her home to inform Miss Chen's brother.
When Mr Chen arrived at the scene, he broke down in despair.
Said Madam Xu: "He kept crying and shouting to his sister, 'Why do you always go to the foodcourt so early? Your work shift does not even start this early."
An ambulance arrived 10 minutes later and Miss Chen was later pronounced dead.
Miss Chen's sister, Madam Chen Meiying, a 52-year-old housewife, told Chinese Daily Lianhe Wanbao that her sister loved helping people.
She added that her sister would take complimentary newspapers every day and give them to her colleagues and their patients at the hospital.
She said: "Before our mother passed away eight years ago, she persuaded my sister to stop doing it. But she insisted on helping people and continued doing so."
Miss Chen frequented Xin Wang Coffee and Tea House. She had another older sister and one younger sister.
According to stallholders, she was polite and well liked by everyone.
An otah seller, who wanted to be known as Ah Meng, said: "She was very friendly and would greet everyone around here.
"She was a very good person."
