Bronx woman stabbed to death in apartment

A 56-year-old woman have been found stabbed to death in a Bronx apartment early Friday, police said.

A man seen on video entering and later leaving the Olmstead Ave. building, part of the Castle Hill Houses, is being sought for questioning.

Officers responding to a 3:37 a.m. 911 call found the victim stabbed in the groin. Medics rushed her to Jacobi Medical Center but she could not be saved.

No weapon was recovered and police said it was not yet clear whether the victim lived where she was attacked.

Neighbors said they knew little about the victim, who lived alone. The NYPD had blocked off all of the second floor of the building.

A security guard laughed as he showed the Daily News a logbook for the building indicating a colleague had marked the residents as “all safe” the night of the murder.
