The woman reportedly stabbed her septuagenarian mother repeatedly on Sunday evening (local time) then hacked off her head with a kitchen chopper, before police arrived to find their apartment engulfed in flames, The Standard said.
The unidentified "killer", believed to have been in her forties, was declared dead at the scene after leaping out of the flat naked, the paper said.
Neighbours at the building in Hong Kong's Kowloon district reported hearing a heated argument before the apparent murder-suicide, local media said.
Last month, police arrested a 15-year-old boy in the city's New Territories after he allegedly killed his mother and sister with a kitchen chopper - a common weapon in domestic violence cases.
