Two bones were recovered this week from debris in a manhole at the site of the World Trade Center, marking the first discoveries in more than a month in the ongoing search for human remains from the September 11, 2001, terrorist attack. The bones were found in a fourth manhole underneath a service road on the western edge of the World Trade Center site, said Ellen Borakove, spokeswoman for the medical examiner's office. One bone was recovered Tuesday and another Wednesday, she said. More than 210 body parts have been found inside manholes since October 19. The discoveries sparked outcry from family members of victims, and authorities launched a new search for remains.
