Coast Guard finds four missing boaters 'in good health' off Key West

The U.S. Coast Guard said Wednesday that it had rescued four boaters one day after they failed to return home as scheduled from a snorkeling trip off Key West. 

A rescue crew reached the missing vessel around 5 p.m. Wednesday, about 40 miles northwest of Key West. All four people onboard were reportedly in good health. A Coast Guard plane spotted the boat earlier Wednesday following a search that covered nearly 4,000 square miles by air and sea.

Authorities previously reported that the boaters left Banana Bay Resort in a 25-foot boat on Tuesday for a snorkeling trip about six miles north of Key West.

A concerned family member contacted the Coast Guard Tuesday evening when they didn't return as scheduled by 4 p.m.

The missing boaters had been identified as 48-year-old David Thompson, 28-year-old Adam Kelley, 15-year-old Joshua Thompson and 11-year-old Evan Thompson.
