US marshals are on the hunt for three Suffolk County sex offenders who disappeared after Hurricane Sandy.

Marshals launched Operation Shore Restore in December to track down offenders who were displaced during the hurricane, authorities said. There are about 1,000 sex offenders in the county, and marshals focused on 500 in the operation.

Authorities found 450 living in registered homes, while 40 had relocated because of the storm. They were found living with family members, in hotels, and in homeless shelters after their homes were damaged.

“There were 10 we felt had absconded as a result of the hurricane, and left,” said Charlie Dunne, the US marshal for the Eastern District of New York.

Seven so far have been located and arrested, but three have not been found yet.
