KUTTAWA, Ky. — Bleeding and alone, 7-year-old Sailor Gutzler had just survived a plane crash that killed her family. She had walked through about a mile of woods and thick briar patches, wearing a short-sleeve shirt, shorts and no shoes in near-freezing temperatures when she saw a light in the distance.The beacon led her to Larry Wilkins’ home, police said, and she knocked on the door. Wilkins answered to find a thin, black-haired girl, whimpering and trembling.“I come to the door and there’s a little girl, 7 years old, bloody nose, bloody arms, bloody legs, one sock, no shoes, crying,” Wilkins, 71, said Saturday. “She told me that her mom and dad were dead, and she had been in a plane crash, and the plane was upside down.”Federal Aviation Administration officials arrived at the crash scene Saturday to try to determine why the small Piper PA-34 crashed, killing four people, including the girl’s parents, Marty Gutzler, 48, and Kimberly Gutzler, 46, authorities said. Also killed were Sailor’s sister, Piper Gutzler, 9; and cousin Sierra Wilder, 14. All were from Nashville, Ill. The bodies have been sent to Louisville for autopsies.
