"Boaters from Sarasota Bay south to Gasparilla are requested to be aware of the possibility of a body or small aircraft debris floating in this area. Boaters who observe anything should immediately contact the Coast Guard using marine radio on channel 16," they added, noting that divers will also be searching near the crash area.

FAA records show that Christian had not been a pilot for a long time, having earned his license on July 21, according to the ABC station WWSB.

In his most recent Facebook post, Christian reflected on making his first solo trip on March 21.

"I flew solo for the first time today! Felt so proud to finally achieve something I've been wanting to do since I was 8 years old." he wrote, sharing that he began taking lessons the previous December and was about halfway through the process of getting his private pilot license.

"Thanks for putting up with my early morning lessons and late night studying Misty Kath; it will all feel worth while when we can fly to the Keys for a weekend away with Lily and Harper soon," he added.

In a comment, his wife replied, "So, so proud of you!!! I cannot wait for all our flying adventures."

An investigation was launched the next day after the FAA asked Venice police to check with the airport for the overdue airplane, police said.

That morning, recreational boaters found the floating body of an adult woman in the Gulf about 2.5 miles west of Venice Beach, according to police.

After spotting the plane's wreckage about a third of a mile offshore in approximately 15 feet of water, divers found the juvenile inside, Thorpe said at Monday's press conference.
