An elderly woman was found dead in her Queens home on Thursday — and cops took a person of interest into custody.

Lillie Hill, 81, was found unconscious by police responding to a 911 call inside her home on 146th Street between Sutter Avenue and Rockaway Boulevard in South Jamaica around 3:30 p.m., according to the NYPD.

Photos captured cops stationed outside her fenced home, just blocks away from John F. Kennedy Airport.

The Office of the Chief Medical Examiner will determine Hill’s cause of death, and an investigation remains ongoing.
