TEQUESTA, Fla. — Hundreds of family members, friends and classmates took part in a Sunday night prayer vigil for two missing 14-year-olds from South Florida who disappeared while fishing in the Atlantic Ocean.

Hours earlier, the U.S. Coast Guard found the teens' 19-foot boat capsized off some 67 miles off Ponce de Leon Inlet in Volusia County. There was no sign of Perry Cohen or Austin Stephanos, who were last seen just before heading to sea on Friday afternoon.

The Coast Guard continued searching throughout the night. The overturned fishing boat was spotted about 11 a.m. Sunday. A Coast Guard helicopter lowered a rescue swimmer who confirmed the registration numbers of the boat. Petty Officer Steve Lehmann said the boat will be anchored in place while search-and-rescue efforts continue.

Officials said they've searched some 25,000 square miles since the boys were reported missing.

The teens were last seen Friday afternoon buying $110 worth of gas before heading in the direction of the Bahamas to fish.

The prayer service took place at Jupiter Christian School where Stephanos has attended since kindergarten.

NFL Hall of Famer Joe Namath, who is Cohen's neighbor, said during a news conference that both of the boys are experienced boaters.
