Posted: Thursday, May 2, 2013, 3:01 AM No remains at 9/11 site NEW YORK - Using a pulley system and sheer brawn, police removed a suspected 9/11 plane part from between two buildings near the World Trade Center site, and the medical examiner said no potential human remains had been found there. "It's a piece of history, and we tried to preserve it as best we could," said NYPD Deputy Chief William Aubry, who leads the forensic investigation division. Aubry said they didn't do any damage to the 255-pound metal piece when they moved it. The medical examiner's office sifted through sediment at the site for days, but found no potential human remains. - AP A Purple Heart 68 years later...
