Investigators are blaming Superstorm Sandy for damaging electrical wiring that touched off last week's boardwalk fire in Seaside Park and Seaside Heights — and warning that similar danger could be lurking elsewhere.

Ocean County Prosecutor Joseph Coronato says "compromised wiring" could be underneath other boardwalks, businesses or homes exposed to flood waters from the Oct. 29 storm. He's urging property owners to have inspections done.

Federal and county investigators said at a news conference Tuesday that the boardwalk fire began accidentally Thursday in wiring that dates to the 1970s, and was located under a custard stand and a candy shop. The blaze destroyed more than 50 businesses in the two towns.

Gov. Chris Christie's administration is using Sandy-recovery money to pay for debris removal and to rebuild the burned businesses.
