By Ap Reporter PUBLISHED: 16:24 EST, 17 September 2013 | UPDATED: 05:32 EST, 18 September 2013 The devastating fire that engulfed part of a Jersey shore boardwalk and dozens of businesses was caused by wiring that was damaged by Hurricane Sandy. The Seaside Park, New Jersey boardwalk emerged relatively unscathed from the October 29 storm compared to its neighbor Seaside Heights. But Sandy left her indelible mark after all, last Thursday when a raging fire blazed through 80 buildings across three blocks of the resort town. The fire began at a frozen custard stand, where aged wiring that had been compromised by salt water and sand sparked what would eventually become an inferno, federal and county investigators said at a Tuesday news conference.
