The crash killed Sailor's parents, Marty Gutzler, 48; and his wife, Kimberly Gutzler, 46; Sailor's sister, Piper Gutzler, 9; and a cousin, Sierra Wilder, 14. All were from Nashville, Illinois.
Marty Gutzler was flying the plane, which reported engine trouble and lost contact with air traffic controllers around 5:55 p.m. CST, authorities said. Controllers tried to direct the pilot to an airport 5 to 7 miles from the crash scene.
About 40 minutes later, 911 dispatchers received the call from Wilkins.
The Gutzlers had been visiting family in Key West, Florida, and stopped in Tallahassee, Florida, on the way back to Mount Vernon, Illinois. Gutzler was a licensed commercial pilot and flight instructor, according to the FAA website.
