Debris that may have contained bits of bone from victims of the World Trade Center attacks was used to fill potholes and pave city roads, according to court papers filed on Friday.

The charge was made in an affidavit filed in Manhattan federal court in an ongoing case filed in 2005 by family members of those killed in the attacks against the city. They say the city did not do enough to search for remains, denying victims a proper burial.

Eric Beck, a construction worker employed at the Fresh Kills landfill in the borough of Staten Island, where the rubble was taken after the Twin Towers fell, said in his affidavit that the process of sifting through the debris was rushed.
