NYC OFFICIALS SEEK HUMAN REMAINS AMID PLANE DEBRIS

This Friday, April 26, 2013, photo provided by the New York City Police Department shows a piece of landing gear that authorities believe belongs to one of the airliners that crashed into the World Trade Center on Sept. 11, 2001, that was found wedged between a mosque and another building, in New York. Police say the medical examiner's office will complete a health and safety evaluation to determine whether to sift the soil around the buildings for possible human remains. 

The New York City medical examiner's office plans to resume searching for human remains two blocks from the World Trade Center after the sudden discovery of an airplane's landing gear.

Medical examiner's spokeswoman Ellen Borakove told The Associated Press on Saturday that the alley behind a mosque site will first be tested as part of a standard health and safety evaluation.

Borakove says sifting for human remains will begin at 8 a.m. Tuesday.

The New York Police Department has declared the alley a crime scene, documenting it with photos and restricting access.

Authorities say the rusted landing gear is believed to be from a Sept. 11 hijacked plane. Police were guarding the area as a crime scene Saturday.
