11:15 A.M. SUNDAY UPDATE | The Coast Guard continued the air and water search for missing boater Fraser Horne Sunday.
Sunday rescue crews patrolled a 3,200 square-mile area in the Gulf of Mexico in the hunt for the 63-year-old Cortez man, who was reported missing Friday evening when he didn't return home as scheduled.

ORIGINAL STORY | The U.S. Coast Guard and other area law enforcement agencies are searching the Gulf of Mexico for a missing boater from Cortez.
Fraser Horne, 63, departed Egmont Key aboard his 30-foot boat, Golden Rush, and did not return home on time Friday, the U.S. Coast Guard said.
Horne's wife contacted authorities about 6:15 Friday evening to report her husband missing.
The Coast Guard launched a 29-foot response boat with small crew from Station Cortez and a MH-60 Jayhawk helicopter crew from Air Station Clearwater to begin the search.
They were joined by rescue boats from the Hillsborough County Sheriff's Office, Holmes Beach Police Department, Manatee County Sheriff's Office, and Florida Fish and Wildlife Conservation Commission.
The Jayhawk crew found Horne's boat at 11:15 p.m. Friday about 5 miles northwest of Mead Point. A rescue swimmer lowered from the Coast Guard helicopter reported the boat's engines were left on but the vessel was in neutral.
Horne's wallet, keys and shoes were found on the boat.
The Coast Guard is asking boaters to keep a lookout and contact Coast Guard Sector St. Petersburg watchstanders at (727) 824-7506 with any information about Horne's disappearance.
