As state officials investigate what caused the Sapelo Island dock collapse, there are questions surrounding the gangway’s construction and how many people it should have supported.

A ferry connecting an island off the coast of Georgia resumed operations Monday while the investigation to see what might have caused a deadly dock collapse that killed seven people continues.

At least seven people were killed Saturday after part of a ferry dock collapsed on Georgia's Sapelo Island, according to a spokesperson for the state agency that operates it.
