CAPE CORAL, Fla.- Federal agents are searching a boat at the Tarpon Point Marina in Cape Coral, but so far, nothing suspicious has been found.

The supervisor with Customs and Border Protection said the captain did not go through Customs when he entered the US through Stuart, so the boat had to go through the routine search once it docked in Cape Coral.

All three people on board were US citizens.
