A Gibbsboro firefighter died Friday from complications involving a leg injury he suffered during a mandatory training exercise nearly three weeks earlier. According to the U.S. Fire Administration, Gibbsboro volunteer firefighter William "Bill" Gerace died because of a pulmonary embolism, which an autopsy found was directly attributed as a complication of a leg fracture he sustained during live burn training April 10. The USFA said in a release Tuesday that Gerace was advancing a hoseline during the training exercise when the nine-year veteran suffered a spiral fracture to his right fibula.
