/*Sharon Lee Hil*/l was brutally stabbed inside her sixth floor /*Springfield Gardens*/ apartment. She was found by a relative yesterday afternoon.
/*Police Commissioner Ray Kelly*/ identified the killer as the victim's 38-year-old "emotionally disturbed adopted sister," with whom she lives.
The woman fled the scene, but was arrested after assaulting another woman.
She was taken to /*Queens Hospital Center*/ for psychiatric evaluation. Charges are pending.
Hill was stabbed multiple times, with pieces of her head cut off.
She may have had a loud argument with the adopted sister before she was killed.
Kelly said investigators are looking into claims by neighbors that they called 911, but police did not respond.
