Investigators to probe jetty where Fernandez's boat crashed

U.S. Sen. Marco Rubio is asking for an investigation into the safety of the rock jetty off South Beach where a weekend boat crash killed Miami Marlins pitcher Jose Fernandez and two others.

In a letter Wednesday, the Florida Republican asked the Coast Guard and Army Corps of Engineers to closely examine the jetty, which he says has long been a hazard to boaters. Rubio says the danger is particularly acute at night when the low-lying rocks are difficult to see.

The Coast Guard has said navigational aids meant to guide boats away from the jetty at the mouth of Miami's port were working when the crash happened early Sunday. The Florida Fish and Wildlife Conservation Commission is investigating the crash.

A public memorial for the 24-year-old star pitcher is set Wednesday afternoon.
