EAST ROCKAWAY - Investigators will now begin carefully examining the boat that sank off Oyster Bay on July 4, killing three children.

The "Kandi Won" was lifted to the surface by FBI divers yesterday afternoon. The 34-foot Silverton was then moved to the Oyster Bay Marina.

Nassau police say the boat will be examined for obvious signs of damage like holes in the craft that would have caused it to take on water. The vessel appeared essentially in tact when it was floated to the surface of the water, although there is a visible crack at the top and the canopy has since been removed.

The boat is now at the Nassau County Police Marine Bureau in East Rockaway for further examination.

Investigators say they will also be looking into whether the boat was overcrowded.

Three children, all under the age of 13, drowned when they were trapped in the boat's cabin. None of the 24 survivors was seriously hurt.

In a statement issued through an attorney, the Treanor family says it is distraught over the pending criminal investigation after this tragic accident.
