At 9am on Friday, Shameera Basha would have been in a celebratory mood.
She would have finished the final paper for her O levels after months of hard work preparing for the examination.
In August, the 16-year-old student from Tanjong Katong Girls' School had tweeted: "Just can't wait for Os to end, I want to watch good movies all day and snuggle in bed."
Tragically, her seat was empty in the examination venue at her school Friday. The Secondary 4 student never got to sit her final paper, biology, which started at 8am and ended at 9am.
On Thursday, she was found with two fatal stab wounds in a bedroom at home, an executive flat in Tampines.
The family's Indonesian domestic helper, Tuti Aeliyah, 28, who was also in the room, was arrested.
Tuti was charged with murder on Friday. It is understood that the charge was read to her in a hospital in the presence of a field magistrate.
From all indications, Shameera had a bright future ahead of her. But all her grieving parents can do now is ponder on what could have been.
Neighbours and friends have described Shameera as an intelligent and nice girl.
She was a high achiever who represented her school in competitions such as the Singapore Mathematical Olympiad this year.
