NEW YORK (AP) — As the unidentified remains of those killed on September 11, 2001 were returned to the World Trade Center site on a foggy Saturday morning, a group of protesters made their voices heard during the solemn procession.

“Don’t put them in the basement!” Rosemary Cain, who lost her firefighter son at the trade center, said Thursday. “Give them respect so 3,000 souls can rest in peace!”

The group of victims’ family members say their loved ones’ remains should be stored in an above-ground monument separate from the museum. About a dozen wore black bands over their mouths at the site.

Other family members support the plans, which have been in the works for years.

The remains were moved from the Office of the Chief Medical Examiner on Manhattan’s East Side at dawn Saturday, accompanied by police and fire department vehicles with lights flashing but no sirens.

The remains will be transferred to an underground repository in the same building as the National September 11 Memorial Museum.

The repository will be available for family visits but will be overseen by the medical examiner. Officials hope that improvements in technology will eventually lead to the identification of the 7,930 fragmentary remains.
