As of 5 p.m., the U.S. Coast Guard was still searching for the missing people, said Petty Officer Jose Hernandez — a Coast Guard spokesman.

The Coast Guard rescued eight people who were on the boat that flipped over about 16 miles south of Key West, Hernandez said.

Two Coast Guard cutters and other units from Coast Guard Sector Key West are involved in the search and rescue operation, Hernandez added.

This is a developing story and will be updated as more information becomes available.
