SINGAPORE - The elderly woman's bloodied body had been sent for an autopsy after her grisly death.
But her death was far more gory than initially thought - her eyes, tongue and a part of her right lung were missing.
Police recovered the eyes and tongue a day after the stabbing.
But the portion of lung remains missing, five months after the incident.
This was revealed during on Monday's coroner's inquiry into the deaths of Madam Rosaline Lim, 75, and her daughter, Ms Andrea Tay Su Lin, 51.
In the early hours of June 4, Madam Lim's body was found in her sixth-storey flat at Block 105, Ang Mo Kio Avenue 4. She had multiple stab wounds.
At the foot of the block lay her daughter's dismembered body.
The mother and daughter had a tempestuous relationship from about 10 years ago, when Madam Lim's mother died.
Ms Tay blamed Madam Lim for the death, and felt that her mother was going after her next, casting spells on her so that she could take over ownership of their jointly-held HDB four-room flat.
This was revealed in the statement that Mr Peh Hock Leong, Ms Tay's former boyfriend, gave to the police. He is the father of Ms Tay's daughter, Germaine Ng, 17.
After Ms Tay got pregnant with Germaine, she divorced her then husband and moved in with Mr Peh in Malaysia.
She returned to Singapore about a decade ago.
Mr Peh believed Ms Tay had some form of mental illness. (See report on right.) But investigators found no record of her ever seeking treatment at the Institute of Mental Health.
On June 4, Germaine had been woken by the sound of her mother and grandmother arguing.
