According to WAFB 9, the two were about to graduate from Louisiana State University, where Jean Luc was a student of engineering and Giselle studied veterinary medicine.
At a press conference on Wednesday, Williamson County Sheriff Mark Elrod stated, "It does appear that the flight did break up in the air.
The school released a statement saying, "We are devastated to hear this news, and our thoughts and prayers are with the entire Doucet family and all those close to them.
The LSU community as a whole, but especially those who know and love these two students and those who were hoping to share graduation with them, are devastated by this.
According to the Advocate, Lucius Doucet, a Baton Rouge-based physician who was regarded by his peers as a "exceptional surgeon" who enjoyed flying, was the owner of the little aircraft.
Three family members perish as the plane disintegrates in midair. According to Williamson Cosmetic Center, "Dr. Doucet was not only a superb surgeon, but also a kind man who touched the lives of numerous individuals within our community.
Everyone who had the honor of knowing him felt his kindness and empathy, and his dedication to his patients was unsurpassed.
Elrod said that they will keep looking through "a rather large debris field" that stretched over half a mile left by the plane's wreckage on Thursday, May 16.
A National Transportation Safety Board official suggested on Thursday that the incident may have been caused by severe weather, as reported by the Advocate.
At a press conference, NTSB aviation accident investigator Aaron McCarter stated, "If weather wasn't the cause of the accident, weather was a factor in the accident.
Around 12:05 p.m. on Wednesday, May 15, emergency personnel got a 911 call from a resident reporting that they had seen debris and an explosion and suspected a plane crash.
It became apparent very quickly that this would not be a search and rescue operation, but rather a search and recovery operation," Elrod stated.
According to News Channel 5, audio from air traffic control addressed the plane beginning to descend from 9,000 feet and indicated there were alternatives for it to land 16 miles north.
Air Traffic Control persisted in attempting to contact the aircraft, but the audio did not make it evident how the pilot answered. The tower said, "Sounds like contact lost.
Responding to the crash were Franklin Fire, Williamson County EMA, Williamson Health EMS, and the Williamson County Sheriff's Office.
