PITTSBURGH (AP) — A district attorney says he found no criminally reckless behavior related to the installation of duct work that collapsed in a Pittsburgh area school injuring some students and staff last year.
As a result, Allegheny County District Attorney Stephen Zappala Jr. says he won’t be filing criminal charges in the April 2012 collapse at Shaler Area Elementary School.
Zappala says the duct work collapsed when a metal cable support system failed.
He said Wednesday that the cable system was not specified for use by the architect but that his investigation found that it was an acceptable substitute, if used properly.
Zappala said he cannot determine if the cable was used the right way because the manufacturer’s standards were “ambiguous.”
