The investigation into the brutal killing and castration of a man in Queens takes a shocking turn. Police now say the apartment where his mutilated body was found belonged to his own daughter.

That woman, Brigitte Harris, is being treated at Bayley-Seton Hospital in Staten Island and has been there for several days after the castration death of her father.

Police have been looking for Harris, 26, who calls herself Lady Vengeance and the "Original Dark Angel."

On her MySpace profile, she plays the song "Ghostflowers," with dark lyrics that talk about being avenged and killing.

She last logged in on Sunday, saying her mood was depressed and that she would like to meet "anyone who can save me."

Police want to talk to her about the murder of 55-year-old Eric Goodrich, who police say lived in a Staten Island duplex with members of his extended family.

He was found mutilated in the attic of the Far Rockaway house Sunday after someone called 911.

Sources tell CBS 2 News that the man had been castrated.

"Nothing like this really happens, so it's shocking," one neighbor said.

Harris rented the upstairs apartment, which was the scene of the gruesome murder.

Police were at the apartment all day Sunday. Neighbors watched as the body was finally carried out.

"After the whole day they took the body, and they took another bag, which was probably part of the body," said neighbor Veronica Vega.
