The U.S. Coast Guard will examine lighting on the Miami Beach jetty involved in a boat crash that killed Jose Fernandez and two other men last month.

Fernandez's crash remains under investigation.

Rear Admiral Paul Thomas said in a letter to U.S. Senator Marco Rubio that the Coast Guard is commissioning a new analysis of the north and south jetties at the entrance to a channel that runs past the southern end of Miami Beach. The letter says an analysis performed last November found that aids to navigation in the area met boaters' needs.
