A deranged woman was busted this morning in connection with the brutal murder of her adopted sister, who was found with her nose and ears sliced off in her Queens home, police sources said.

The 38-year-old suspect is emotionally disturbed and lived with the victim, Sharon Lee Hill, 58 in the Baisley Park Houses, police sources said. Police tracked the assailant down after she allegedly attacked another woman. She was taken to Queens Hospital Center for observation and is currently in police custody, police sources said.

Hill was found inside her living room at about 2:30 p.m. Sunday by a third sister who lives on Long Island, sources said. Neighbors heard the victim and the suspect arguing earlier in the day.
