KOTA KINABALU: The stepsister of the late Zara Qairina Mahathir told the coroner's court that she had no first-hand knowledge of how Zara's mother cared for her, adding that she had never lived with the deceased.

Malianah Mahathir, 25, the 81st witness, said she only knew of Zara's life and family from social media posts as well as information from her father.

When questioned by lawyer Shahlan Jufri, who represents Zara's mother, Malianah said she had seen photographs of the family on the Facebook accounts of Zara, her mother and her father.
