The Federal Aviation Administration confirmed that seven people were aboard the plane and Rutherford County officials confirmed that at least one person had died. The identities of the occupants were not disclosed by authorities.

But Lara’s daughter, Elizabeth Hannah, issued a text to members of the Remnant Fellowship, asking for prayers and saying the aircraft "had to go down for a controlled, quick landing," WTVF-TV of Nashville reported.

Hannah identified those on the plane as her parents, her husband Brandon, and Remnant leaders David and Jennifer Martin, and Jonathan and Jessica Walters.

It was unclear who was piloting the plane or who had reportedly died in the crash. But a trailer for the Laras’ YouTube series states that Joe Lara is a pilot.
