Fire Consumes Remnants of Deutsche Bank Building

Remnants of the Deutsche Bank office building located near ground zero mysteriously caught fire August 18, 2007. According to reports, more than 700 bones and fragments were discovered in the contaminated skyscraper from mid-2005 through June 2007. The building was in the process of being dismantled; it was noted to be a "constant headache for redevelopers" and was contaminated with toxic dust and debris from the demolition of the WTC. The questions will remain how did these "fragments" end up on a rooftop of a nearby building and what other evidence was located at this site?
