Tribute center run by volunteers with ties to 9/11 to move

NEW YORK (AP) — A tribute center that's been hosting tours led by volunteers with personal ties to the Sept. 11 attacks is moving and expanding.

Years before the National September 11 Memorial & Museum opened, when visitors saw nothing but the wreckage, artifacts from the attack and recorded memories were kept by the center.

The center's exhibition includes recovered artifacts and items such as the helmet Ielpi wore for months, digging through dirt and chaotic remains before his dead son was finally discovered.
